Abstract
An image forming apparatus includes a controller for controlling at least a photoconductor drum and a fuser to operate independently of each other. In such an apparatus, at least one of the photoconductor drum and the fuser is provided with an electrical or mechanical member, such as a clutch for selectively coupling a driving system and a rotary member, which is operative independently, and the controller provides such a control that the electrical or mechanical members of the photoconductor drum and the fuser are responsive to signals applied thereto to start or stop the operations independently in timing, respectively.
