いる転写装置。 In a transfer device using a transfer drum that supports a transfer paper on a transfer drum wrapped with a dielectric sheet and performs one to multiple transfers to the transfer paper to form a copy image, a transfer position in contact with a photoreceptor drum. Alternatively, a pressing means is provided at a position of the dielectric sheet near the dielectric sheet to deform it by pressing from the transfer paper supporting surface side to make it out of contact with the photoreceptor drum, and when the pressure of the pressing means is released, the restoring force of the dielectric sheet deforms the photoreceptor. A transfer device using a transfer drum, characterized in that the transfer drum is in contact with the drum.
