PURPOSE:To reduce a time loss for controlling a picture density by detecting loading of an original, feeding the original, in an original automatic feed mode. CONSTITUTION:A copying machine body 100 and an external additional device (ADF)200 are coupled by a signal. In the periphery of a photosensitive drum 33, high voltage electrifier 31, transfer electrifier 40, etc. are placed, an original image is formed on the photosensitive drum 33, and a toner image is transferred to transfer paper by the transfer electrifier 40. An image forming mode can be set to an original static mode or an original automatic feed mode, and in case of the original automatic feed mode, loading of an original is detected, feeding the original. |
