Conveyer-member control device, image forming apparatus, and drive control method |
摘要 |
A detecting unit detects a conveying speed of a conveyer member. A driving unit drives the conveyer member. A first control unit performs a first feedback control of the conveying speed based on detected conveying speed and a predetermined target conveying speed. A second control unit detects a rotation speed of the driving unit and performs a second feedback control of the rotation speed based on detected rotation speed and a predetermined target rotation speed. When a determining unit determines that the detecting unit is anomalous, a switching unit switches from the first feedback control to the second feedback control. |
