Abstract
A cartridge removably mountable to an image forming apparatus, including: a developing unit having a developing roller; two support mechanisms each configured to rotatably support the developing unit by a rotary shaft at an each end of the cartridge; and a biasing member provided on one support mechanism and configured to apply a biasing force to bring the roller into contact with a photosensitive drum, wherein a force against the biasing force is applied to the developing unit to rotate the developing unit to separate the roller from the drum, and in a projection plane orthogonal to the rotary shaft, an action point on which the biasing force acts is arranged between a first line connecting rotation centers of the roller and the drum and a second line passing through the support shaft in parallel with a slide direction of the support shaft slidably supported by the one support mechanism.
