    Abstract: A developing cartridge includes a first gear, a second gear, and a protrusion. The first gear is rotatable about a first axis extending in a predetermined direction. The second gear is configured to engage with the first gear and rotatable about a second axis extending in the predetermined direction. The protrusion extends in the predetermined direction and circularly movable together with rotation of the second gear. The first gear is movable in a direction away from the second gear from a first position to engage with the second gear to a second position to disengage from the second gear.

    Abstract: 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.

    Abstract: An image forming apparatus including a drawer and a main body. The drawer includes a frame holding a photosensitive drum rotatable about an axis extending in a first direction and a drawer-side connector including a drawer-side electrical contact part. The main body includes: a housing including a main body-side electrical contact part; a shaft extending in the first direction; a unit removably insertable to the housing; and a connection member. One end in a third direction intersecting with the first and second directions of the unit is fitted to the housing and the other end is supported to the shaft via the connection member. The main body-side connector is supported to the unit. The drawer-side electrical contact part and the main body-side electrical contact part are interconnected when the drawer is accommodated.

    Abstract: An image forming apparatus includes an image forming engine, a re-conveyance path configured to guide a sheet, on which an image is formed by the image forming engine, to be switched back and re-conveyed toward the image forming engine. The apparatus also includes a discharge tray, and a discharge path configured to guide the sheet in a sheet discharge direction toward the discharge tray. A stack lever is configured to contact a top surface of the sheet on the discharge tray and press the sheet toward the discharge tray. A guide member is configured to form a part of the re-conveyance path, extend up to a position downstream of the stack lever in the sheet discharge direction above the stack lever, and guide the sheet being conveyed along the re-conveyance path, between the guide member and the stack lever.
