ABSTRACT:
A developing apparatus is so set as to face the developed section of the electrostatic latent image-forming plane of the photosensitive drum, and causes a magnetic developing agent to be magnetically conducted to the electrostatic latent image-forming plane. Further, a magnet roll is so provided as to face that portion of the electrostatic latent image-forming plane of the photosensitive drum which has passed the developed region, thereby adsorptively removing the unnecessary particles of the developing agent which are deposited on the electrostatic latent image-forming plane. Therefore, the developing apparatus, though possessed of a relatively simple arrangement, has the advantages of suppressing the occurrence of the aforesaid tailing phenomenon, and enabling a distinct impression to be transcribed on a copy sheet with the reproducibility of fine lines prominently improved.
