PROBLEM TO BE SOLVED: To suppress fluctuation of speed of an intermediate transfer body occurring before and after the entry of a toner into a transfer part between an image carrier and the intermediate transfer body to suppress the occurrence of a color shift image.SOLUTION: In an image forming apparatus, a developing unit 12M having been in a separation state from a photoreceptor drum 9M before image formation is brought into contact with the photoreceptor drum 9M, and after a contact position on the photoreceptor drum 9M where the developing unit 12M is brought into contact with the photoreceptor drum 9M passes a primary transfer part T1 by the rotation of the photoreceptor drum 9M, a primary transfer roller 13M is applied with a voltage from a transfer power source 51M. |
