Abstract: If an input of a continuous image forming job is received, a time for interrupting the continuous image forming job is decided based on an image area ratio of a toner image that is formed on a latent image carrier through the continuous image forming job and a predetermined number of formed images (the number of passed sheets) that is formed until a predetermined type of abnormal image is generated when continuous image formation is performed at the image area ratio. During an interruption period of the continuous image forming job, an idle rotation in which the latent image carrier rotates in a state in which the toner is not supplied to the latent image carrier by the developing unit is performed, and the cleaning process is performed.

Abstract: A motor controller calculates a motor torque command based on motor speed and causes a motor to generate a torque corresponding to the motor torque command, to drive a machine load coupled to the motor. The motor controller includes a speed compensator that makes, when a speed compensation torque is calculated based on the motor speed, frequency characteristics of the speed compensation torque for the motor speed exhibit a low frequency cutoff characteristic so that steady-state gain in frequency response is less than a maximum gain value. A torque adder generates a motor torque command by adding to the existing motor torque command an externally input feedforward torque signal and the speed compensation torque.

Abstract: The surface coated member comprises a substrate and a hard coating layer coated on the surface of the substrate. The hard coating layer comprises a lower layer composed of at least one layer and an upper layer composed of at least one layer and coated on the surface of the lower layer. When FU stands for a peeling load under which the upper layer starts to peel away from the surface of the lower layer and FL stands for a peeling load under which the lower layer starts to peel away from the surface of the substrate, the ratio (FL/FU) is 1.1 to 30. Thereby, it is possible to obtain a surface coated member that has excellent toughness and high fracture resistance, and that can be applied to a long life tool having excellent fracture resistance even under severe cutting conditions such as metal cutting, e.g., steel cutting and interrupted cutting of cast iron that bring a strong impact on a tool's cutting edge. It is also possible to maintain excellent fracture resistance and increase resistance to wear.
