摘要：
An image forming apparatus capable of removing a toner remaining on the transfer belt (toner supporting member) with a simple configuration. The image forming apparatus includes an intermediate transfer belt that moves with charged toner supported on the surface thereof; a cleaner roller that is rotated while being pressed onto the intermediate transfer belt; a power source for supplying potential for electrically attracting the toner to the cleaner roller from the intermediate transfer belt; and a pretreatment roller that is pressed onto the intermediate transfer belt upstream from the cleaner roller in the moving direction of the intermediate transfer belt.
