ABSTRACT:
A paper folding member and a jam sensor are disposed downstream of the position at which a transfer drum confronts an image carrying body and in proximity to the transfer drum. The paper folding member is a platelike member substantially assuming a right-angled triangle, and has an edge that projects more to the upstream side at a position closer to the transfer drum pulling side. When a paper jam occurs, engagement between gears for transmitting a driving force from the image carrying body to the transfer drum is released, so that the transfer drum becomes freely rotatable in its normal rotational direction. When the transfer drum is pulled, a recording sheet is gradually taken out of a cleaning device first from its portion on the side opposite to the transfer drum pulling side, and is inserted between the paper folding member and the transfer drum as the transfer drum is rotated. As a result, the recording sheet can be taken out of the apparatus without getting separated from the transfer drum.
