ABSTRACT:
An image forming apparatus has an image bearing member bearing images thereon and movable, and a transfer medium bearing member provided in pressure contact with the image bearing member and bearing a transfer medium thereon and rotatable. The transfer medium bearing member has a sheet member for bearing the transfer medium thereon, and an elastic layer supporting that area of the sheet member bearing the transfer medium thereon from the inside of the sheet member. A voltage is applied to the transfer medium bearing member to transfer the images on the image bearing member to the transfer medium born on the sheet member. The sheet member has an area not fixed to the elastic layer. The transfer medium bearing member is rotated with a potential difference created between the image bearing member and the sheet member before the operation of transferring the images on the image bearing member to the transfer medium born on the sheet member is started.
