Abstract
Abstract The copying machine includes an image forming unit for forming a reproduced image of an original document on a copying sheet, a data input unit for entering data necessary for image formation, and a timing control for performing timing control of the image forming unit for image formation in response to the entered data. The image forming unit includes a rotary member for forming a transfer image on the copying sheet, and a feeder unit for repeatedly supplying the copy sheets to a transfer station. The input unit has an instruction device for selecting the position of the reproduced image on the copying sheet. The timing control device is provided with a feed control having a switch to be actuated by the image forming unit and a timer associated with the switch, and with a timer control unit for controlling operation of the timer for shifting feed timing of the feed control in response to the instruction data supplied from the instruction device.
