Abstract
An image forming apparatus includes first and second image bearing members on which toner images are to be formed, a conveying member, and a conveying member position index detecting device for detecting a conveying member position index provided on the conveying member. The apparatus also includes an image bearing member position index detecting device for detecting image bearing member position indices provided on the second image bearing member, an adjusting device for adjusting a rotational speed of the second image bearing member, and a controller for controlling the adjusting device so as to adjust a position of an image bearing member position index correspondingly to the conveying member position index, on the basis of detection results of the conveying member position index detecting device and the image bearing member position index detecting device.
