ABSTRACT:
A process unit mounted in a housing of a laser printer includes a developing device for supplying toner to a latent image formed on a photosensitive member so that a visible toner image corresponding to the latent image is formed on the photosensitive member, a first chamber provided adjacent to the developing device, a second chamber connected via an opening to the first chamber, and a feeding mechanism for feeding waste toner to the first chamber, the waste developer being removed from the photosensitive member by a cleaning device after the visible toner image is transferred to a recording sheet. Thereby, the waste developer fed to the first chamber is further fed via the opening to the second chamber so that the waste developer is stored in the first and second chambers.
