摘要： The detachment of a feed roller rotatably supported by a holding portion provided in the main body of an apparatus, and held detachably in the axial direction thereof is restricted by a locking device. The locking device is made movable to a lock position and a lock releasing position for permitting the detachment of the feed roller. Further, when the locking device is in the lock releasing position when a sheet stacking portion is mounted, the locking device is moved to the lock position by a position changeover device in operative association with the mounting operation of the sheet stacking portion.

摘要： An image forming apparatus includes a rotatable image carrying member, a rotatable transfer member cooperative with the image carrying member, and a fixing unit having a fixing nip for nipping and feeding the recording material discharged from the transfer nip while fixing the toner image. In addition, a bowing amount measuring unit measures a bowing amount of the recording material, a storing portion stores a target bowing amount, and a speed controller controls a feeding speed of the recording material. The storing portion stores a plurality of target bowing amounts, which are selectable depending on kinds of the recording material, and the speed controller controls the feeding speed in the fixing nip, and then controls the feeding speed so that the bowing amount is substantially zero at the time when a trailing edge of the recording material leaves the transfer nip.
