摘要： A developing cartridge includes: a casing configured to accommodate therein toner; a developing roller; a supply roller configured to supply the toner to the developing roller; a layer thickness regulation blade in contact with a circumferential surface of the developing roller; a developing electrode electrically connected to the developing roller; and a supply electrode electrically connected to the supply roller and the layer thickness regulation blade. The supply electrode includes: an electrode member electrically connected to a rotation shaft of the supply roller and movable in a direction perpendicular to the rotation shaft; and a connection member in contact with and electrically connecting the electrode member and the layer thickness regulation blade. The electrode member is movable relative to the connection member in the direction perpendicular to the rotation shaft in a state where the electrode member is in contact with the connection member.

摘要： A photosensitive drum is rotatable about a first axis extending in a particular direction. A frame rotatably supports the photosensitive drum. A developing roller is rotatable according to driving force about a second axis extending in the particular direction. A surface of the developing roller contacts a surface of the photosensitive drum through toner. A resistance generating member generates a resistance torque TQ1 serving as resistance between the frame and photosensitive drum in a case where the photosensitive drum rotates relative to the frame. In a case where the developing roller rotates according to the driving force in a state where the surface of the developing roller contacts the surface of the photosensitive drum through toner, the resistance torque TQ1 is smaller than a torque TQ2 that causes the photosensitive drum to rotate due to friction between the surface of the developing roller and the surface of the photosensitive drum.

摘要： A drum cartridge includes: a drum frame to which a developing cartridge including a storage medium having an electrical contact surface is detachably attachable; a photosensitive drum; a transfer roller; and a conveying roller. The drum is rotatable about a first axis extending in a first direction and positioned at one end portion of the frame in a second direction. The transfer roller is rotatable about a second axis extending in the first direction and in contact with the drum. The conveying roller is rotatable about a third axis extending in the first direction and separated from the transfer roller in the second direction. A first opening of the frame is positioned between the transfer roller and the conveying roller in the second direction. The electrical contact surface is exposed to an outside through the first opening in a case where the developing cartridge is attached to the frame.

摘要： A process cartridge includes a drum cartridge and a developing cartridge attachable to and detachable from the drum cartridge. The developing cartridge includes a developing roller, a pressing protrusion and an engagement protrusion. The drum cartridge includes a photosensitive drum, a locking member engageable with the engagement protrusion of the developing cartridge attached to the drum cartridge, and a pressing member disposed between the locking member and the photosensitive drum. The locking member is pivotable between a restricting position engaged with the engagement protrusion to restrict detachment of the developing cartridge from the drum cartridge and a non-restricting position disengaged from the engagement protrusion to allow detachment of the developing cartridge from the drum cartridge. The pressing member is configured to contact the pressing protrusion of the developing cartridge attached to the drum cartridge for pressing the developing cartridge toward the photosensitive drum.

摘要： A developing cartridge may include a housing including an outer surface, a small-diameter gear, a large-diameter gear, a first gear, and a moving member. The small-diameter gear may include a first engaging portion positioned on at least a portion of a peripheral surface of the small-diameter gear. The large-diameter gear may be positioned farther from the outer surface than the small-diameter gear from the outer surface. The large-diameter gear may be rotatable together with the small-diameter gear. The first gear may include a second engaging portion, a first end surface, a second end surface, and at least one protrusion. The moving member may include a contact portion configured to move the moving member from one position to another position in a state where the contact portion is in contact with the protrusion.
