Abstract
The present invention provides an image forming apparatus having an image bearing member for bearing a toner image, and a transfer rotary member for forming a nip between the transfer rotary member and the image bearing member, the transfer rotary member being provided at its surface with a solid layer and serving to transfer the toner image from the image bearing member onto a transfer material at the nip, and wherein a moving speed of a surface of the transfer rotary member at the nip is greater than a moving speed of a surface of the image bearing member at the nip, and a surface friction force of the transfer rotary member is greater than a surface friction force of the image bearing member by 3 to 20 times.
