Abstract
A process cartridge includes a photosensitive drum and a first casing rotatably supporting the photosensitive drum. The process cartridge also includes a developing roller configured to develop an electrostatic latent image formed on the photosensitive drum with toner, a supplying roller configured to supply the developing roller with the toner, and a second casing rotatably supporting the developing roller and the supplying roller and containing the toner. A rotatable coupling is provided with a projection and operatively connected to the supplying roller and the developing roller so that the coupling can transmit a rotational force to the supplying roller and the developing roller, and at least a part of the coupling being movable in a direction perpendicular to a rotational axis of the coupling. Rotatable gears are configured to transmit the rotational force from the coupling to the developing roller, and a spring urges the at least part of the coupling toward the first casing in the direction perpendicular to the rotational axis of the coupling.
