Claims

[Scope of utility model registration request]

The image forming unit frame that rotatably supports the photosensitive drum is configured to be switchable between a connected state in which it is attached to the main body and a non-connected state in which it is pulled out to the front side of the main body, and this image forming unit frame is attached to the main body. In a copying machine configured such that the photosensitive drum is drivingly connected to a drive source on the main body side via a one-way clutch, a lock release mechanism is provided on a switching lever that switches the transport unit frame between an active state and a non-active state. Removal of a photosensitive drum of a copying machine which is connected in an interlocking manner so that when a switching lever is switched to a non-operating position, the photosensitive drum is forcibly rotated in a direction to release the lock of the one-way clutch by the lock release mechanism. mechanism.
