Abstract:
1. An image forming apparatus, comprising: an image bearing member that has a photosensitive layer formed on an outer peripheral surface thereof; a first conductive member that makes contact with the photosensitive layer of the image bearing member; a bias application device that applies a bias including an alternating current bias to the first conductive member; and a control portion that controls the bias application device, wherein image formation is performed on a surface of the image bearing member while the image bearing member is made to rotate, and the image forming apparatus is capable of executing a heating-up mode in which, at a time of non-image formation, in a state where the image bearing member is made to rotate at a velocity lower than that used at a time of image formation, an alternating current bias having a frequency higher than that used at the time of image formation and a peak-to-peak value twice or more as large as a discharge start voltage between the first conductive member and the image bearing member is applied to the first conductive member to cause a surface of the image bearing member to be heated up.
