Abstract
In existing image forming apparatuses, it is difficult to maintain each of a primary transfer member and a secondary transfer member at an optimum potential. An image forming apparatus includes a voltage maintenance element connected to a secondary transfer counter roller and a primary transfer member. The voltage maintenance element maintains each of the secondary transfer counter roller and the primary transfer member at a predetermined potential or higher. By using the voltage maintenance element, each of a secondary transfer roller and the primary transfer member is set to an optimum potential by a single transfer power supply.
