PURPOSE:To obtain copy pictures of high quality even if the moving speed of a copying machine body is not constant, by providing a rotating body which is rotated in accordance with movement of the machine body and controlling the image formation timing and the speed of an image forming means synchronously with the rotation of the rotating body. CONSTITUTION:A machine body 1 is placed on an original 2 to operate a switch 40, and a power source is turned on to start operations of a heater of a fixing device 13, light sources 19 and 20, etc. Operation start timings and operation speeds of a photosensitive body 3, a developing device 5, a resist roll 9, a fixing roll of the fixing device 13, a grip roll 25, other carrying roll which feed a transfer paper to the photosensitive drum 3, a charging charger 4, etc. where the moving speed of the machine body 1, namely, the scanning speed has influences upon the forming state of copy pictures are synchronized with the operation start timing and the speed of a driving roll 22 which is rotated in accordance with movement of the machine body 1. Even if the speed of the machine body 1 is slightly varied and is not constant, individual devices are operated in accordance with this variance to form correct toner images without enlarging and reducing. |
