Abstract
An image forming apparatus includes an image bearing member, an image forming device for forming a toner image on the image bearing member, a recording material, a transfer device for transferring the toner image from the image bearing member to the recording material, a transfer belt for carrying the recording material, a first cleaning member, a second cleaning member, and a voltage control device. When continuously forming toner images on sheets of the recording material, a detection toner image is formed on the image bearing member between images to be formed on sheets of the recording material. The first cleaning member cleans the image bearing member. The second cleaning member cleans the transfer belt. The voltage control device controls the voltage applied to the transfer device so that the number of operations to clean the detection toner image is higher for the second cleaning member than the first cleaning member.
