Document Type and Number:
Japanese Patent JP2500905
Kind Code:
B2
Abstract:
PURPOSE: To provide an electrophotographic device whose constitution is simple and which is miniaturized and has high resolution.
CONSTITUTION: A photosensitive drum 6 having a fixed magnet 7 inside is used. After an electrostatic latent image is formed, the photosensitive drum 6 is brought into contact with a two-component magnetic developer 12 in a developer storage reservoir 11 and the developer 12 is attracted to the surface of the photosensitive body 6 by magnetic force. Further, when an electrode roller 15 on which an AC voltage is applied passes, toner remains on only an image part and it is developed and actualized. Thus, the electrophotographic device which is miniaturized and has high image quality and excellent high speed adaptability can be obtained.
