ABSTRACT:
An image forming apparatus passes a photosensitive sheet between a pair of pressure rollers which are normally pressed against each other. A pressure relieving mechanism is provided so as to release the pressure between these rollers if it is detected that the photosensitive sheet is not being properly transported to the pressure rollers such that the operator can remove the cause of the abnormal condition.
