Abstract
An image forming apparatus including: an image bearing belt that bears an image; an image creation unit that transfers the image on the image bearing belt; a first driving source; a driving roller that is rotationally driven by the first driving source and causes the image bearing belt to move; a transfer roller that has a concaved portion in a circumferential surface, forms a transfer nip by the transfer roller making contact with the image bearing belt, and transfers the image on the image bearing belt to a recording material; a second driving source that rotationally drives the transfer roller; a material type determination unit that determines a type of the recording material; and a control unit that controls a rotational frequency of the transfer roller when the recording material is nipped by the transfer nip based on information of the type determined by the material type determination unit.
