Abstract:
In an image forming apparatus, developer remaining on a photosensitive member as transfer residual developer is caught temporarily by a catching portion. In a collecting process, the transfer residual developer caught by the catching portion is returned to the photosensitive member, the transfer residual developer then is transferred onto a conveyor member, and the transfer residual developer is collected by a collecting portion. In the collecting process, the presence or absence or an amount of the transfer residual developer transferred onto the conveyor member is measured.
