20120321345 | Cartridge - A cartridge including: a housing including a first side wall and a second side wall which are opposed to each other; a driving input member provided to the first side wall and is configured to rotate; and a first rotary member provided at an outer side of the first side wall and is configured to rotate about a first rotational axis in response to a rotational driving force from the driving input member, wherein the first rotary member includes a protrusion protruding to the outer side, wherein the first rotary member is configured to be moved relative to the first side wall in a direction along the first rotational axis, and wherein an end portion of the first rotary member at an opposite side of the first side wall is configured to be displaced in a direction crossing the first rotational axis. | 12-20-2012 |
20140241736 | Image Forming Apparatus Including Cartridge for Protecting Photosensitive Drum - An image forming apparatus includes a main body and a cartridge attached to the main body. The cartridge includes: a casing extending in a longitudinal direction; a photosensitive drum extending in the longitudinal direction; and a separating member that is detachably attached to the casing. The photosensitive drum has a peripheral surface and is positioned in confrontation with the endless belt as a result of attachment of the cartridge to the main body. The separating member is attached to the casing and separates the photosensitive drum from the endless belt when the main body is packaged while the cartridge is attached to the main body. The separating member includes first and second end portions disposed on both end portions of the casing, and a connecting portion connecting the first and second end portions and is configured to cover the peripheral surface. | 08-28-2014 |
20140270849 | Cartridge - A cartridge including: a housing including a first side wall and a second side wall which are opposed to each other; a driving input member provided to the first side wall and is configured to rotate; and a first rotary member provided at an outer side of the first side wall and is configured to rotate about a first rotational axis in response to a rotational driving force from the driving input member, wherein the first rotary member includes a protrusion protruding to the outer side, wherein the first rotary member is configured to be moved relative to the first side wall in a direction along the first rotational axis, and wherein an end portion of the first rotary member at an opposite side of the first side wall is configured to be displaced in a direction crossing the first rotational axis. | 09-18-2014 |
20140363189 | Cartridge Provided with Coil-Shaped Electrode Member - A cartridge includes: a rotation body; and an electrode member. The electrode member is configured to supply the rotation body with electric power from an external electrode provided outside of the cartridge. The electrode member includes: a contact portion; and an urging portion. The contact portion is configured to be contacted with the external electrode. The urging portion is in a shape of a coil formed by winding a wire rod and configured to urge the contact portion toward the external electrode such that the contact portion is pivotally moved about the urging portion. | 12-11-2014 |
20150037068 | Image Forming Apparatus - An image forming apparatus may include: a process cartridge, an apparatus body and a spacing member. The process cartridge may be detachably mountable to the apparatus body and include a photosensitive unit having a photosensitive member, a developing unit having a developing roller, and a driving input part into which a driving force from the apparatus body is configured to be inputted. The apparatus body may include a driving input member which is configured to input the driving force. Additionally or alternatively, the spacing member may be attached to the process cartridge and configured to space the photosensitive member and the developing roller. The spacing member may include a first cover part which is located between the driving input part and the driving input member and covers at least a portion of the driving input part. | 02-05-2015 |
20160139557 | Image Forming Apparatus Having Spacing Configuration for Process Cartridge - An image forming apparatus may include: a process cartridge, an apparatus body and a spacing member. The process cartridge may be detachably mountable to the apparatus body and include a photosensitive unit having a photosensitive member, a developing unit having a developing roller, and a driving input part into which a driving force from the apparatus body is configured to be inputted. The apparatus body may include a driving input member which is configured to input the driving force. Additionally or alternatively, the spacing member may be attached to the process cartridge and configured to space the photosensitive member and the developing roller.
