Abstract

A developing unit, which is attachable to and detachable from a photosensitive member unit, includes: a developing roller; a housing in which a holding space that holds toner is formed; and a pressing receiving portion that receives pressing force from a pressing member. The housing includes a first bottom portion that projects toward an outer side of the holding space, and a second bottom portion that projects toward the outer side of the holding space, in a state in use. When viewed in a direction of a rotation axis of the developing roller, at least part of the pressing receiving portion is located in a space surrounded by the first bottom portion, the second bottom portion, and a tangent line tangent to both an outer wall of the first bottom portion and an outer wall of the second bottom portion.
