ABSTRACT:
An image forming apparatus includes an image bearing member for bearing an electrostatic image; a developer carrying member, opposed to the image bearing member, for carrying a one component developer which is charged to a predetermined polarity by friction between the developer and the developer carrying member; an electric field generating device for generating, between the image bearing member and developer carrying member, an electric field for developing the electrostatic image on the image bearing member with a reverse development method; a regulating member for regulating an amount of the developer on the developer carrying member; and a voltage applying device for applying to the regulating member, a voltage having a polarity opposite the predetermined polarity.
