Abstract
An image recording apparatus has a photoconductive drum and a roller, e.g., developing roller, in pressure contact with the photoconductive drum. The photoconductive drum rotates on its rotational axis and has drum gears rotatable about the rotational axis. The drum gears are at opposite ends of the rotational axis. The roller is in pressure contact with the photoconductive drum and rotates on its rotational axis substantially parallel with the rotational axis of the photoconductive drum. The roller has roller gears rotatable about its rotational axis. The roller gears are at opposite ends of the rotational axis and in mesh with the drum gears. At least one of the roller gears is provided with a one-way clutch which is locked only when a drive force is applied to the roller gear.
