    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 includes an image carrying member, a driving device, a charging member, a cleaning member, a voltage applying device, a torque detector for detecting the torque of the driving device, a storage for storing a predetermined torque value Tc, and a control portion. The control portion obtains as Ton the torque when the charging voltage is applied to the charging member and obtains as Toff the torque when no charging voltage is applied to the charging member. Let the torque observed when no charging voltage is applied at an early stage of use of the image carrying member be represented by Toff(0), then, when the relations Toff(0)

    Abstract: 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.
