20150277354 | Cartridge - A cartridge including a housing, a driving receiving part, a rotary member configured to rotate, and move in an axis direction thereof while rotating, and a detected member configured to move in the axis direction by receiving a driving force from the rotary member, wherein the rotary member includes a main body part having a first surface facing the detected member in the axis direction and a second surface positioned at an opposite side of the first surface in the axis direction, an operating part arranged on the first surface and configured to apply a force for moving the detected member in the axis direction to the detected member, and an operated part arranged on the second surface and configured to receive a force for moving the main body part in the axis direction. | 10-01-2015 |
20150277359 | IMAGE FORMING APPARATUS PROVIDED WITH LIGHT GUIDE AND LIGHT SOURCE - An image forming apparatus includes: a main casing; a light source; and a photosensitive cartridge. The light source is provided in the main casing and configured to emit a light. The photosensitive cartridge is mountable in the main casing in a mounting direction. The photosensitive cartridge includes: a photosensitive drum; a light guide; a first wall and a second wall. The photosensitive drum has a surface. The light guide is configured to guide the light emitted from the light source to the surface of the photosensitive drum to eliminate static on the surface of the photosensitive drum. The second wall is spaced apart from the first wall in a first direction that crosses the mounting direction. The light source is disposed between the first wall and the second wall when the photosensitive cartridge has been mounted in the main casing. | 10-01-2015 |
