摘要： An image forming apparatus includes an image bearing member, a conductive member, a bias application device, and a control portion. The image bearing member has a photosensitive layer formed on an outer peripheral surface thereof. The conductive member is disposed so as to make contact with an inner peripheral surface of the image bearing member and has a dielectric property. The bias application device applies a bias including an alternating current bias to the conductive member. The control portion controls the bias application device. The image forming apparatus is capable of executing a heating-up mode in which an alternating current bias having a peak-to-peak value twice or more as large as a discharge start voltage between the conductive member and the image bearing member is applied to the conductive member to cause the surface of the image bearing member to be heated up.

摘要： An image forming device includes an image carrier on the surface of which a toner image is formed, a cleaning member arranged in contact with, for cleaning, the surface of the image carrier, a charging member for electrostatically charging the image carrier, a bias applying device, and a control portion. The bias applying device applies a charging bias having DC and AC biases superimposed on each other to the charging member. The control portion controls the charging bias applied to the charging member by the bias applying device. As the AC bias applied to the charging member, the control portion uses, in a first period from the start of use of the image carrier to a predetermined time thereafter, a first AC bias and, in a second period subsequent to the first period, a second AC bias higher than the first AC bias.

摘要： An image forming apparatus includes image forming units, static eliminating sections, a mode switching section, and an exposure switching section. The static eliminating sections outputs first and second light. The mode switching section switches a state a between a first mode in which all of the image forming units are operated and a second mode in which only a first image forming unit is operated. In a second image forming unit located upstream next to the first image forming unit, the exposure switching section causes the image bearing member of the second image forming unit not to be irradiated with the first light and causes the image bearing member of the first image forming unit to be irradiated with the second light in the second mode.
