Abstract
An image forming apparatus includes a case, a photosensitive drum, a developing cartridge, a supporting member set, a force-exerting member set and a resilient member. The photosensitive drum forms a toner image. The developing cartridge, movably disposed within the case, includes a developing tank and a developing roller. The developing roller, mounted on the developing tank and positioned opposite the photosensitive drum, transfers toners to the photosensitive drum. The supporting member set is disposed on an inner wall of the case. The force-exerting member set, disposed on an outer wall of the developing tank, interacts with the supporting member set to maintain steady contact pressure between the developing roller and the photosensitive drum. The resilient member, disposed between the developing tank and the case, provides a restoring force for counteracting a weight of the developing tank and urging the developing roller towards the photosensitive drum.
