Title: Color image forming device
Inventor: MATSUO HIROYUKI
IPC: G03G15/01
Filed: 1989-12-29
Abstract: PURPOSE:To prevent the potential of a background part from rising at the time of overlapping colors one another and toner from scattering in exposure by advancing black reversal development prior to other-color normal development and making the surface potential of an electrostatic latent image formation member high after the member passes through a 1st electrostatic charging means. CONSTITUTION:The surface of a photosensitive body 12 in its initial state is set to a specific background potential by an electrostatic charger 1 and then exposed to an image by an image exposing means 3 to form an electrostatic latent image whose potential is lower than a specific value. A black developing means 7 is used first and black toner is stuck on a photosensitive body 12, which is charged again electrostatically and uniformly by a relay 1 above the surface potential of the photosensitive body 12 which carries toner. Then a relay 2 lowers the surface potential of the photosensitive body 12 below a specific value which is a development potential to invert the polarity of the toner. When normal development is performed for respective colors other than black, a rise in background part potential at the time when color images are overlapped one another is eliminated and the toner is prevented from scattering in the exposure since the potential of the photosensitive body 12 is inverted in potential.
