In an image forming apparatus adopting a cleanerless process, there is provided a technique of preventing deterioration of picture quality due to photoreceptor filming or color mixture. An image forming apparatus of a cleanerless process in which a toner image is formed on an image bearing body by a developing unit, and a toner remaining on the image bearing body is collected by the developing unit, includes an intermediate transfer belt made of laminated layers of plural conductive materials different from each other and having a belt surface onto which the toner image is transferred from the image bearing body at a specified transfer position, and a transfer unit configured to press the intermediate transfer belt to the image bearing body at the specified transfer position and to apply a specified bias voltage to the intermediate transfer belt, wherein with respect to the plural conductive materials of the intermediate transfer belt, a layer closer to a side of either one of the toner transferred from the image bearing body and the transfer unit, where negative polarity is set, has a higher volume resistance value.
