<p>PURPOSE: To shorten necessary time to form an image by reducing wasteful use of a sheet. CONSTITUTION: An opening-closing detecting device 135 is arranged to detect an opening-closing condition of an upper guide plate 111b becoming openable and closable to process a jam caused in an intermediate tray 111. A MPU 137 continues loading operation of a sheet to the intermediate tray 111 or feeding operation of the sheet from the intermediate tray 111 when the opening- closing device 135 does not detect an opening condition of the upper guide plate 111b until its situation is processed when a situation (such as a jam) to be processed by hands of an operator is caused in a place except the intermediate tray 111.</p> |
