A photoreceptor unit includes a photoconductive drum assembly, a housing to enclose the photoconductive drum assembly to be rotatable therein, a handgrip rotatably formed on the housing, and a stopper to prevent the housing with the photoconductive drum assembly from becoming lopsided toward its preponderant side of the housing with respect to a center of rotation of the handgrip when the housing is lifted up by the handgrip.
