Abstract
A driving unit is controlled so that a driving state where an image bearing member is driven with a first potential difference formed between a brush member and the image bearing member at a contact portion where the image bearing member is in contact with the brush member transitions to a stopped state where the image bearing member stops being driven with a second potential difference formed, the second potential difference having an absolute value less than that of the first potential difference.
