Claims

[Scope of utility model registration request]

In an image forming apparatus, an electrostatic latent image is formed on an image carrier through an imaging system, and the electrostatic latent image is developed by a developing device having at least a non-magnetic sleeve number. A developing device for an image forming apparatus, characterized in that a concavo-convex portion is formed along the circumferential direction and approximately matches the light distribution characteristics of the imaging system.
