Abstract

The present invention discloses a mono-component developing device comprising a rotatable drive roller which confronts a rotatable photoreceptor, a flexible member arranged on the exterior surface of the drive roller and having a peripheral length greater than a peripheral length of the drive roller, an elastic pad provided on the side opposed to the side confronting the photoreceptor of the drive roller, and an elastic plate arranged at both ends of the flexible member in an axial length thereof. In the developing device having the above construction the flexible member onto which a toner is supplied is pressed toward the photoreceptor by the elastic pad while being pressed by the elastic plate in the axial direction of the flexible member, so that the flexible member contacts with the surface of the photoreceptor on the side confronting the photoreceptor of the drive roller to supply the toner to an electrostatic latent image formed on the photoreceptor surface.
