<p>PURPOSE:To improve operability by providing a knob attached so as to be freely engaged and fitted on the shaft end of a transfer roller, a switch operated by interlocking to the engagement of the knob and the shaft end of the transfer roller, and an attaching/detaching means separating a driving system for rotating a photosensitive body. CONSTITUTION:The knob 14 attached to the shaft end of the transfer roller 5 so as to be freely engaged and fitted, the switch 16 operated by interlocking to the engagement of the knob 14 and the transfer roller 5, and the attaching/ detaching means 11 separating the driving system 13 rotating the photosensitive body by interlocking to the operation of the switch 16, are provided. The switch 16 is operated by interlocking to the engagement of the knob 14 with the transfer roller 5, and a driving roller 4a for rotating a photosensitive belt 3, and a driving source 13 are separated in response to the operation. Therefore, a load from the side of the transfer roller 5 is reduced, and the transfer roller 5 can be manually rotated with a little torque. Thus, only the knob 14 is engaged with the transfer roller 5, so that processing at the time of paper jamming is easily carried out, and the operability is improved.</p> |
