Abstract:
1. An image forming apparatus, comprising a photoreceptor member that is driven by a driving motor to form an image thereon; and a control section to control the driving motor so as to drive the photoreceptor member at a constant velocity; wherein the control section is provided with: wherein, during an initial operating time, the control section deactivates the feed forward controlling section, while only activates the feedback controlling section to drive the photoreceptor member so as to measure a driving toque of the driving motor, and selects a first parameter from the parameters, corresponding to the driving toque measured; and wherein, after the first parameter is selected, the control section activates both the feed forward controlling section, which employs the first parameter, and the feedback controlling section, to drive the photoreceptor member so as to conduct an image forming operation for forming the image thereon.
