Abstract: An image forming apparatus has a photosensitive member, a charging member, an exposing device, a developing device, a transfer member, a polishing member, a driving device, a voltage applying device, a torque detector, and a control portion. The photosensitive member has a photosensitive layer and a surface protection layer formed on the surface of the photosensitive layer. The polishing member has an elastic layer on its circumferential surface, and rotates with a linear velocity difference from that of the photosensitive member. The torque detector detects the torque of the driving device. The control portion estimates an attachment condition of discharge products to the surface of the photosensitive member based on the torque of the driving device detected by the torque detector. When the torque is equal to or higher than a predetermined value, the control portion performs an image degradation suppression process.

Abstract: 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.

Abstract: An image forming apparatus has an image carrying body, a first electrically conductive member, a bias application device, and a controller. The first electrically conductive member makes contact with the photosensitive layer of the image carrying body The bias application device applies a bias containing an AC bias to the first electrically conductive member. The controller controls the bias application device. The image forming apparatus can execute, while no image formation is being performed, a temperature raising mode in which, with the first electrically conductive member in contact with the image carrying body outside the image formation region, an AC bias having a peak-to-peak value twice as high as the discharge start voltage between the first electrically conductive member and the image carrying body is applied to the first electrically conductive member to raise the temperature of the surface of the image carrying body.

Abstract: An image forming apparatus includes an image bearing member, a first conductive member, a bias application device, and a control portion, and performs image formation on a surface of the image bearing member while making the image bearing member rotate. The image forming apparatus is capable of executing a heating-up mode in which, at the 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 the 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.

Abstract: An image forming apparatus has an image forming portion, a fixing device, a temperature sensing device, and a control portion. The fixing device has a fixing member having a heated rotary member and a pressing member forming a fixing nip by making contact with the heated rotary member. The temperature sensing device senses the surface temperature of at least one of the heated rotary member and the pressing member in a plurality of regions in the axial direction. The control portion estimates the thickness distribution of the surface layer of at least one of the heated rotary member and the pressing member in the axial direction based on the time taken for the surface temperature in the plurality of regions to reach the predetermined temperature, and thereby estimates the lifetime of at least one of the heated rotary member or the pressing member based on the estimated thickness distribution.
