Abstract
A developing unit and a photosensitive unit respectively have engaging mechanism parts that fit in each other in the longitudinal direction so as to integrate the developing unit and the photosensitive unit. The developing unit includes, as the engaging mechanism part, a first holding member to hold the front end part of a drum shaft. The photosensitive unit includes, as the engaging mechanism part, a second holding member to hold the rear end part of a roller shaft. The first holding member and the second holding member are provided in a slidable manner in a direction in which the developing roller and the photosensitive drum separate from each other, and furthermore are biased toward a direction in which the developing roller and the photosensitive drum come close to each other.
