Abstract

PURPOSE:To reduce the deterioration of a photosensitive drum and a transfer material carrier belt by controlling the drives of respective motors to make the difference of rotary speed as small as possible. CONSTITUTION:A control means controls to make the difference small causing between the driving force of a driving means which drives a large load and the driving force of the driving means which drives a small load between a first driving means 9 or a second driving means 13 (a drum motor 9, a belt motor 13) during the time from starting driving of the first and second driving means (the drum motor 9, the belt motor 13) till moving to a steady driving condition and/or during the time from keeping steady driving condition till stopping driving. Consequently, the friction causing between an image carrier driven by the first driving means 9 and the transfer material carrier belt means driven by the second driving means 13 can be made small. Thus the deterioration of the image carrier and the transfer material carrier belt means can be reduced by this.
