    • A drive control system for controlling a drive motor in response to external command signals. The system comprises a first control arrangement for obtaining numerical values corresponding to amounts of successive intermittent operations of the drive motor responsive to respective external command signals, summing the obtained numerical values, and subtracting from a current sum of the numerical values a numerical value corresponding to a non-operation time period during which the drive motor is held at rest between the successive intermittent operations. The system further comprises a second control arrangement for inhibiting the operation of the drive motor responsive to the next command signal, for a length of time corresponding to the current sum after the drive motor has completed each of the intermittent operations, whereby the temperature of the drive motor is kept below an upper limit.

    • An image forming apparatus includes an image carrier that rotates by power generated by a driving source. A power transmission system transmits the power from the driving source to the image carrier. The power transmission system includes a coupling member to attenuate oscillation. The coupling member includes a viscous fluid, male and female fittings, and a rotating resistor. The viscous fluid provides a resistance against rotation of the image carrier. The male and female fittings are mutually fitted and rotatably supported on a rotary shaft of the image carrier penetrating through the male and female fittings in a direction in which they are mutually fitted. The rotating resistor is accommodated together with the viscous fluid in an accommodation space defined by a recess of the male fitting and a bottom inner surface of the female fitting. The rotating resistor integrally rotates with the rotary shaft.
