Abstract
In a charging device used in a cleanerless image forming apparatus and including a charging brush in contact with an image bearing member, a scraping member is provided which is in contact with the charging brush with a predetermined amount of indentation overlap on an upstream side of a contact portion between the charging brush and the image bearing member with respect to a rotational direction of the charging brush. With such an arrangement, the developer, which is scraped from the charging brush by the scraping member and then adheres onto the image bearing member, is recharged by the charging brush so as to be collected by a developing-cleaning device.
