Image forming apparatus and control method thereof

摘要

Disclosed herein are an image forming apparatus and a control method thereof. The image forming apparatus includes a plurality of photoconductors, a transfer belt, a plurality of transfer rollers arranged in parallel with the plurality of photoconductors, and a controller rotating the transfer belt under the condition that at least one of the plurality of transfer rollers presses the transfer belt toward at least one of the plurality of photoconductors, interrupting power transmitted to the transfer belt to cause at least another of the plurality of transfer rollers to press the transfer belt toward at least another of the plurality of photoconductors, standing by until rotation of the transfer belt is stopped, after interruption of the power, and controlling the at least another of the plurality of transfer rollers so as to press the transfer belt toward the at least another of the plurality of photoconductors.

主权项

1. A control method of an image forming apparatus which has a plurality of transfer rollers, a plurality of photoconductors and a transfer belt, the transfer belt is interposed between the plurality of transfer rollers and the plurality of photoconductors and pressing the transfer belt to come into contact with the plurality of photoconductors, the control method comprising:
rotating the transfer belt under the condition that the plurality of transfer rollers does not press the transfer belt toward the plurality of photoconductors; interrupting power transmitted to the transfer belt to cause the plurality of transfer rollers to press the transfer belt; standing by until rotation of the transfer belt is stopped, after interruption of the power; and controlling the plurality of transfer rollers so as to press the transfer belt toward the plurality of photoconductors, when rotation of the transfer belt is stopped.
