Abstract
An image forming apparatus that includes an intermediate transfer belt (ITB) that has a mark, a sensor that detects the mark, a driving unit that drives the ITB, and a control unit that controls the driving speed of the driving unit, during a certain period of time after completing a printing operation, according to the detection of the mark by the sensor.
Claims20
An image forming apparatus comprising:
- an intermediate transfer belt (ITB) having a mark;
- a sensor that detects the mark, when the ITB moves the mark to the sensor;
- a driving unit that drives the ITB;
- and
- a control unit that determines a current location of the mark, based on the detection of the mark by the sensor, and changes the driving speed of the driving unit, according to the proximity of the mark to the sensor, during a standby period that occurs after the control unit completes a first print job.
