Abstract: In a sheet feeding device, a main body includes a feeding unit configured to feed a sheet in a feeding direction to a conveying path. A cover is configured to pivot about a first axis relative to the main body between a closed position in which the cover closes the conveying path and an open position in which the cover exposes the conveying path. A plate is configured to pivot about a second axis which is parallel to the first axis and to contact and move away from the feeding unit. The second axis is closer to the cover than to the feeding unit in the feeding direction. In a state in which the cover is in the closed position, at least a part of the cover is positioned on an upper side of the plate so as to be contactable with the plate.

Abstract: A positioning guide is configured to guide a rotational axis of a photosensitive body when a process cartridge is mounted on a main body, and to determine a position of the rotation axis of the photosensitive body with respect to the main body in a mounting state in which the process cartridge has been mounted on the main body. A photosensitive body drive gear is configured to be capable of rotating in a forward and reverse direction and to transmit a rotational drive force to the photosensitive body in the mounting state. A regulating member is configured to be in a lock state and an unlock state. In the lock state, the regulating member prohibits the rotational axis of the photosensitive body from moving in the mounting/removing direction. The rotational axis of the photosensitive body is released from the regulating member in the unlock state.
