To provide a drive with an arrangement capable of avoiding the formation of abnormal images caused by banding or the like, without increasing costs.

Of a plurality of driven members 31Bk, 31Y, 31C and 31M, one driven member 31Bk and the other driven members 31Y, 31C and 31M are fitted with a drive source 32 for the one driven member 31Bk and the other drive source 33 for driving the other driven members 31Y, 31C and 31M together. A driving force from the other drive source 33 designed for the driven members 31Y, 31C and 31M other than the one driven member is transmitted via idlers 34 positioned between the driven members 31Y, 31C and 31M. The driven members 31Y, 31C and 31M are given matching rotary fluctuation phases M1 to M3 during assembly.
