PROBLEM TO BE SOLVED: To prevent a deviation in a transfer, at the time of transferring toner images altogether by driving first and second images carrying means with a common drive source. SOLUTION: A gear G3 is rotated by the transmission of the rotation of a gear G2 by the drive of a gear G1 by a driving motor M1 as a drive source attached to a driving panel 104, so that a photoreceptor drum 10 is driven to rotate. The gear G2 is attached to a driving panel 104. Similarly, gears G4, G5 and G6 are rotated by the gear G2, according to the transmission of the rotation of the gear G2 following the drive of the gear G1 by the driving motor M1 as the common drive source, so that a gear G7 fixed on one shaft of a driving roller 14d for a toner image receptor 14a is driven by the gear G6, to rotate a driving roller 14d and a toner image receptor 14a. Thus, the circumferential speeds of the rotary body drum 10 and the toner image receptor 14a are made uniform so that the deviation in the transfer, at the time of transferring the toner images to the toner image receptor 14a from the photoreceptor drum 10 altogether can be prevented. |
