ABSTRACT:
An electrostatic image forming apparatus has high cleaning efficiency using the electrostatic fur brush method. A photosensitive body having a photoconductive characteristic is charged uniformly. An electrostatic latent image is formed on the surface of the charged photosensitive body by radiating light rays on the area to be developed. The latent image is developed by the dry-type developing method by use of toner charged with same polarity as that of the photosensitive body's surface. The obtained visible image is transferred electrostatically onto the transfer paper. A non-electrically-insulative fur brush 16 removes the remaining toner 20 from the surface of the photosensitive body 14 and an electric potential gradient generator 17 generates an electric potential gradient through the fur brush which transfers the remaining toner 20 to the fur brush 16 from the surface of the photosensitive body 14. The toner to be employed has a substantially uniform particle diameter.
