Title: Electrophotographic device
Inventor: YOSHIDA YUKIMASA
IPC: G03G15/06
Filed: 2000-08-31
Abstract: PROBLEM TO BE SOLVED: To obtain a stable image with high quality by setting the frequencies of the respective AC components of electrifying bias and developing bias so that a beat frequency generated by interference between the AC component of the electrifying bias and that of the developing bias becomes sufficiently small or sufficiently large. SOLUTION: The beat spatial frequency of a photoreceptor 3 is defined as (fd-n×fc)/ v. Provided that (v) is the carrying speed of a transfer material, (fc) is the frequency of the electrifying bias, (fd) is the frequency of the developing bias and (n) is an integer. Then, the originating frequency generated by an AC power source for electrifying E4a and the frequency generated by an AC power source for developing E5a are set so that the beat frequency becomes sufficiently small or sufficiently large. When they are set to be fd-fc=560Hz and the carrying seed is set to be v=50mm, the spatial frequency by which an image variabledensity stripe appears is (fd-fc)/v=25.6 pieces/mm and (fd-2fc)/v=11.2 pieces/mm and it does not become under 10 pieces/mm.  Thus, since the frequency of the image variable-density stripe is sufficiently large, the deterioration of the image quality is not felt by the eye of a person. Besides, even when the frequency of the image variable-density stripe is set to be sufficiently small, the image variable-density stripe is not viewed.
