Abstract: A process cartridge includes a frame and a photosensitive drum supported by the frame, with the photosensitive drum being rotatable about an axis thereof. A coupling is operatively connected to the photosensitive drum such that a driving force can be transferred from the coupling to the photosensitive drum. A developing roller is supported by the frame, with the developing roller being rotatable about an axis thereof. A gear is positioned at a side of the process cartridge, with the gear being rotatable about an axis thereof. The gear has a plurality of teeth, with at least some of the teeth being exposed teeth that are uncovered by the frame and exposed to outside of the process cartridge, and with a tip of at least one of the exposed teeth facing the axis of the photosensitive drum. As measured in the axial direction of the photosensitive drum, the teeth of the gear are shorter than the projection of the coupling.

Abstract: A process cartridge includes a photosensitive drum and a gear portion having gear teeth configured to receive a driving force from outside of the process cartridge. The gear portion includes an exposed portion exposed to outside of the process cartridge. A shortest distance from an axis of the photosensitive drum to a tooth tip of the exposed portion of the gear portion measured along a direction perpendicular to the axis of the photosensitive drum is no less than 90% and no more than 110% of a radius of the photosensitive drum.

Abstract: A process cartridge includes a frame having a slit and a recess formed therein at a side of the process cartridge. A photosensitive drum is supported by the frame, with the photosensitive drum being rotatable about an axis thereof, the photosensitive drum including a first end and a second end opposite to the first end. A developing roller is also supported by the frame, the developing roller being rotatable about an axis thereof. A coupling is operatively connected to the photosensitive drum, with the coupling being rotatable about an axis thereof. A helical gear is positioned at the side of the process cartridge, with the helical gear being rotatable about an axis thereof. The helical gear has a plurality of teeth, with at least some of the teeth being exposed teeth that are uncovered by the frame and exposed to outside of the process cartridge.

Abstract: A cartridge mountable to and dismountable from a main assembly of an image forming apparatus includes a memory, a guide configured to guide a portion-to-be-guided provided in the main assembly and to guide a main assembly contact provided in the main assembly to a memory contact of the memory when the cartridge is mounted in the main assembly, and a grip portion. The guide is provided at a bottom of the cartridge when the cartridge is hung by gripping the grip portion and constitutes a part of a supporting portion configured to support the cartridge when the cartridge is placed on a horizontal placement surface. The guide has a chamfered surface formed by being chamfered. When the cartridge is supported at the supporting portion, the chamfered surface opposes the horizontal placement surface, and a surface of the memory contact is inclined with respect to the horizontal placement surface.

Abstract: A developer accommodating container for accommodating a developer includes: a toner seal member for unsealably sealing an opening of the developer accommodating container; an unsealing member, connected to an end portion of the toner seal member, for unsealing the opening by moving at least a part of the toner seal member; and an auxiliary unsealing member for assisting unsealing by changing a pulling direction of the toner seal member by the unsealing member. The auxiliary unsealing member includes a shaft portion or a projected portion. The shaft portion or the projected portion extends in a longitudinal direction of the developer accommodating container.

Abstract: An image forming apparatus includes an apparatus main-body to and from which a process cartridge can be attached and detached. The process cartridge includes an image carrying member to carry an image, a charging member to charge the image carrying member, a cleaning member to clean the charging member by contacting it, and a force receiving unit to receive a force for moving the cleaning member in a longitudinal direction of the image carrying member. The apparatus main-body includes a slope portion which slopes in a direction in which the process cartridge is attached and contacts the force receiving unit to apply the force in a process where the process cartridge is attached to the apparatus main-body, and the slope portion applies the force to the force receiving unit to move the cleaning member from an inside to an outside of a region where an image can be formed.
