<p>PURPOSE:To prevent the generation of an uneven image caused by the speed difference of a transfer material and an image carrier by driving a first driving system for driving to rotate the image carrier and a specific transfer material carrying roller, and a second driving system for driving to rotate other transfer material carrying rollers, by different driving sources. CONSTITUTION:The titled device is divided into the first driving system A for driving a photosensitive drum 1, and a transfer material carrying roller immediately before said drum, namely, a pre-transfer roller 4, and the second driving system B for driving other transfer material carrying rollers than the roller 4, namely, a pickup roller 2, a resist roller 3, a carrying belt driving roller 51, and a fixing roller 6. Also, said each driving system A, B is provided with each different driving source. In such way, it is prevented that a vibration at the time of intermittence of a clutch extends over the image carrying body 1 or the transfer material of carrying roller 4 immediately before said body through the driving systems A, B, and also, it is prevented that a shift is generated between the carrying speed of a transfer material and the peripheral velocity of the image carrier 1.</p> |
