ABSTRACT:
An image forming apparatus includes a latent image carrier, a charging member, a conductive brush member that cleans the charging member, a developer carrier including magnetic field generating devices having main and auxiliary magnetic poles, a developer scatter preventing member, and a toner accumulation preventing member. A contact pressure of an end portion of the developer scatter preventing member relative to the latent image carrier is set such that a brush, which falls from the conductive brush member and is carried on the latent image carrier, passes through a contact part between the end portion of the developer scatter preventing member and the latent image carrier. The main magnetic pole has an angular width of about 60 degrees or less between opposite pole transition points respectively positioned upstream and downstream of a flux density of the main magnetic pole in the normal direction in a developer conveying direction.
