20140161472 | DEVELOPING DEVICE AND IMAGE FORMING APPARATUS - Disclosed herein is a developing device including: a developer housing section configured to house a developer including toner and carrier; a carrier replenishing section configured to supply the carrier to the developer housing section; a carrier concentration detecting section provided at a position near a carrier replenishment position at which the carrier is received from the carrier replenishing section in the developer housing section, the carrier concentration detecting section being configured to detect a carrier concentration in the developer housing section; and a carrier replenishment determination section configured to determine whether the carrier is properly supplied to the developer housing section on the basis of a result of detecting by the carrier concentration detecting section. | 2014-06-12 |
20140161473 | IMAGE HEATING APPARATUS - An image heating apparatus, including: a rotary member; a heating member configured to heat the rotary member, the heating member being held in contact with the rotary member; a temperature detecting element configured to detect temperature of the rotary member or the heating member; a protection element configured to interrupt power supply to the heating member, the protection element being activated when sensing abnormal rise in temperature of the heating member; and a control portion configured to control the image heating apparatus, wherein, when the temperature detected by the temperature detecting element exceeds a threshold value, the control portion stops rotation of the rotary member. | 2014-06-12 |
20140161474 | IMAGE FORMING APPARATUS - An image forming apparatus includes an image output unit that forms an image with developer, a gathering unit that gathers developer not used by the image output unit as waste developer, plural collection containers that store and collect the waste developer, a transport device that transports the waste developer toward one of the collection containers and includes a discharge portion which is connected to the one of the collection containers, a moving device that moves the collection containers together to respective predetermined arrangement positions including a collection position for connection to the discharge portion and an attachment/detachment position, and a full-state detector that detects that the collection container at the collection position is in an almost full state. A selected one of the collection containers is preferentially moved to the collection position when the other collection container detected by the full-state detector is detached. | 2014-06-12 |
20140161475 | RECORDING MATERIAL IMAGE CAPTURE DEVICE AND IMAGE FORMING APPARATUS - A recording material image capture device includes light sources radiating light to a recording material, an image capture element receiving the light which is reflected on a surface of the recording material, a cover member provided between the image capture element and the recording material so that the reflected light passes through the cover member, a roller pressing the recording material toward the cover member, and an output portion outputting, based on an image captured by the image capture element, a value related to the recording material to which the light is radiated. The roller is a rotating member which rotates along with movement of the recording material, and the roller includes a recess portion which is prevented from contacting with an entire portion corresponding to the image used for determining the recording material, and projecting portions which are brought into contact with the recording material. | 2014-06-12 |
