PURPOSE:To precisely develop both a photosensitive member and a transferring member even if the synchronism of the conveyance of both members is not precisely caught by conveying the transferring member to a pressure developing device in advance before a latent image part which is formed on the photosensitive member arrives at the pressure developing device. CONSTITUTION:If the driving source of the conveyance of the photosensitive member 24 and the driving source of the conveyance of the transferring member 27 are different from each other, the transferring member 27 is conveyed to the pressure developing device 8 in advance before an area in which the latent image of the photosensitive member 24 is formed arrives at the pressure developing device 8. Thus the photosensitive member 24 and the transferring member 27 are precisely overlapped even if such a high control as exactly catching the synchronism of the conveyance of the photosensitive member 24 and the conveyance of the transferring member 27 is not performed. Then, a highly reliable image forming device by which a stable, high-grade and high-powered image can be obtained can be constituted. |
