Abstract
An image forming apparatus includes an image transferring device having a belt transfer unit for effectively performing an image transfer operation. The belt transfer unit includes a transport mechanism transporting a toner image, a scale provided around an entire perimeter of a surface of the transferring member and including at least one colored resin layer, and a scale reading mechanism arranged facing the scale and reading the scale. With the above-described belt transfer unit, a feedback control can effectively be performed to maintain constant reading accuracy and to prevent a voltage leak from a transfer mechanism.
