Abstract:
An image forming apparatus includes an image bearing member; a transfer portion that transfers a toner image; a conveying member that conveys a recording material; a conveying member position index sensing member that senses a conveying member position index fixed to the conveying member in the transfer portion; a toner image position index sensing member that senses a toner image position index fixed to the image bearing member in the transfer portion; a drive member that can control a position of the conveying member in a moving direction of the conveying member and a rotating speed of the conveying member; and a control portion that controls the drive member to position the conveying member position index with respect to the toner image position index reaching the transfer portion based on the sensing results of the conveying member position index and the toner image position index.
