写せしめるものが一般に用いられる。 Conventionally, as a transfer device for multiple transfer, in order to ensure good alignment, the tip of the transfer material is locked with a claw or the like provided on a transfer drum such as a conductive rubber roller or a drum having an insulating layer. Alternatively, it is generally used to hold the transfer material by electrostatically attracting and fixing it onto the drum, bringing the transfer material into contact with the photosensitive drum, and applying a transfer voltage as necessary to transfer the toner image on the drum. It will be done.
この様な構成の装置では、転写ドラムが感光体
に続触する為、感光体の摩耗、ピンホールの発生
等、感光体の損傷が生じ易く、感光体の寿命を縮
めるものである。 In an apparatus having such a structure, since the transfer drum continuously contacts the photoreceptor, damage to the photoreceptor such as abrasion of the photoreceptor and generation of pinholes is likely to occur, which shortens the life of the photoreceptor.

The transfer material P fed at step 6 is transferred to the gripper 1012.
and is gripped by the gripper table 1001 (that the transfer material P is not gripped is detected by the protrusion 1021 of the micro switch). Next, the transfer material conveyed along the cylindrical transfer guide 1013 passes under the transfer corona charger 1014.
The toner image on the photosensitive drum is transferred, and while sliding on the perforated cylinder 1017, the corona discharger 10
22, the toner on the transfer material is made to have the original polarity, that is, the polarity opposite to that of the transfer corona discharger 1014, and when the plurality of transfers are completed, the gripper 101 is applied to the stopper member.
Both sides of 2 hit, and the transfer material is released from the grip. Then, it is scooped up by claws 1020 and sent to the next process. Here, 1015 is a suction device for preventing the transfer material from floating up by itself. Further, the transfer guide 1013 has a movable structure in order to match the transfer length and the circumferential speed of the photosensitive drum 14 and the transfer material, but it may of course be fixed. The same effect can also be obtained by rotating the cylinder 1017 itself. The cylinder is connected to the gear of the photosensitive drum by a gear having an integer ratio, with a gap of 3 to 5 m/m relative to the photosensitive drum, and when a bias 1018 (same polarity as the transfer corona) is applied, the transfer occurs. You can get an even image.

When either the upper or lower cassette is selected using the selection button in the operating section provided at the top of the main body, the pick-up roll 36 rotates as the photosensitive drum rotates and comes into contact with the uppermost transfer material P in the descending cassette, and then descends slightly. Send P out of the cassette. Simultaneously with the operation of the pick-up roll 36, the first timing roll 35 stops, and the transfer material P sent out from the cassette forms a loop and stops instantaneously.
It then reaches the second timing roll 31. The second timing roll 31 stops a little before the transfer material reaches the transfer material P, so the transfer material P hits the second timing roll 31 to form a loop and then stops. Thereafter, the second timing roll 31 is operated in synchronization with the color toner image on the photosensitive drum.
