| 20080279585 | Image forming apparatus - A holding unit turns, while holding a latent image writing unit, centered on a turning axis that is arranged on a main body of an image forming apparatus between an opening position and a closing position with respect to the main body. A positioning unit arranged on the main body positions the latent image writing unit with respect to the image carrier, when the holding unit is at the closing position. A biasing unit biases the latent image writing unit to make a contact with the positioning unit. A shock absorbing unit absorbs a shock received by the holding unit and the latent image writing unit when the holding unit is moved from the closing position to the opening position. | 11-13-2008 |
| 20100080623 | ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS - An electrophotographic image forming apparatus includes a cartridge supporting member movable between an inside position inside the main assembly of the apparatus and an outside position outside the main assembly, a light source, a light guide member, on the cartridge supporting member, for guiding the light from the light source to electrically discharge charge remaining on a drum after a developed image on the drum is transferred onto recording material when the cartridge is in an image forming position, an interrelating member for moving the light source to an operating position where the light enters the light guide member in interrelation with movement of the cartridge supporting member from the outside to the inside positions, and a positioning member positioning the light source at the operating position. | 04-01-2010 |
| 20100202798 | Image Forming Apparatus, Image Forming System, Container for Developing Agent, and Method of Manufacturing Container for Developing Agent - An image forming apparatus is provided. The image forming apparatus includes a mounting part configured to be detachably mountable therein plural types of cartridges having different initial capacities of developing agent; a light emitting device configured to emit light into the cartridge mounted in the mounting part; a light receiving device configured to receive light emitted from the light emitting device and passed through an inside of the cartridge; a determining unit configured to determine that a replacement time of the cartridge has been reached when a ratio of time, during which an output value of the light receiving device exceeds a light reception reference value, exceeds a determination threshold value. The image forming apparatus or the cartridges are configured such that the determination of the replacement time changes according to the initial capacity of the cartridge. | 08-12-2010 |
| 20130315623 | Image Forming Apparatus - A color multifunction printer as an example of an image forming apparatus includes a plurality of cartridges each containing a photoconductor; a support frame configured to support the cartridges arranged in tandem, the support frame being allowed to be pulled out horizontally from a casing of the apparatus to a position in which each of the cartridges is detachable from the support frame; and a plurality of exposure units mounted to the support frame, wherein each of the exposure units is disposed opposite to a corresponding photoconductor and is configured to expose the photoconductor to light to form an electrostatic latent image thereon. Each of the cartridges is configured to be detachable in such a direction that the photoconductor in the cartridge moves away from the corresponding exposure unit upon detachment. | 11-28-2013 |
| 20140044452 | Image Forming Apparatus - An image forming apparatus includes: a main body having an opening; a photoconductor unit including a photoconductor and removably mountable to the main body through the opening by moving the photoconductor unit in a first direction; an exposure member; and a moving mechanism configured to move the exposure member to and away from the photoconductor. The moving mechanism includes: a fixed shaft having an axial line thereof fixed relative to the main body; a first arm including one end portion thereof which is supported rotatably around the axial line of the fixed shaft; a movable shaft having an axial line thereof which is movable relative to the main body; and a second arm including: one end portion supporting the exposure member; and another end portion connected to the first arm via the movable shaft, and the second arm being swingable around the axial line of the movable shaft. | 02-13-2014 |
| 20140212170 | Image Forming Apparatus Capable of Reliably Protecting Exposure Member - An image forming apparatus includes: a main casing; a photosensitive member; a moving mechanism; a movable member; and a cartridge. The photosensitive member is provided in the main casing. The movable member moves between an inside position in which the movable member is inside the main casing and an outside position in which the movable member is at least partly outside the main casing. The movable member includes: a frame; a protection member; and an exposure member. The protection member is fixed to the frame. The moving mechanism moves the exposure member between an exposing position in which the exposure member exposes the photosensitive drum to light and a protected position in which the exposure member is protected by the protection member. The cartridge includes a developer bearing member. The cartridge is supported at the movable member. | 07-31-2014 |
| 20160018782 | Photosensitive Drum Access Configuration for an Image-Forming Apparatus - An image forming apparatus includes a main body, a photosensitive drum detachably attached to the main body, a light exposure member configured to expose the photosensitive member to light, a developer container configured to store a developer to be supplied to the photosensitive drum, and a supporting member disposed in the main body and configured to support the light exposure member and to hold the developer container detachably. The supporting member is configured to, while holding the developer container, move between a light exposure position where the light exposure member is located proximate to the photosensitive drum and a separation position where the light exposure member is separated from the photosensitive drum while the supporting member holds the developer container. | 01-21-2016 |
