Summary: | An image forming apparatus (1) includes a photosensitive member (11) charged to a predetermined polarity, an intermediary transfer belt (6), a primary transfer member (15) forming a primary transfer portion (N1), an electrode member (8) in contact with the inner peripheral surface of the photosensitive member on a downstream side, first and second detecting portion (75a, 75b) to detect a current flowing through or a voltage applied to the primary transfer member and the electrode member, respectively, and a control portion (3), during non-image formation, to execute a setting operation in which the transfer bias to be set during image formation is set. In executing the setting operation, the control portion sets the transfer bias based on a first detecting result detected by the first detecting portion while a voltage is applied to the primary transfer member and a second detecting result detected by the second detecting portion while the voltage is applied to the primary transfer member. |
