ABSTRACT:
A developing device of an electrophotographic apparatus comprising a light-sensitive member for forming an electrostatic latent image, a developing roller comprising a magnetic roller and a sleeve, the developing roller supplying a developer which is to be magnetized in the same polarity as that of the electrostatic latent image while the developer is adhered on the sleeve by a relative-rotational speed between the sleeve and the magnetic roller, and regulating means for regulating the thickness of the developer on the sleeve to be approximately equal to the distance between the light-sensitive member and the sleeve.
