Abstract

See full text

An optical photoreceptor belt is rotated by a pair of belt drive rollers. The belt is positively charged by a main-charger. Latent images having a low electric potential are formed on the belt by exposing the positively charged belt by laser diode units, In developer units, ink having positive electric charge is moved by electrostatic force from develop rollers having a high electric potential to spots of the latent images on the belt having a low electric potential to form the images. The optical photoreceptor belt with images formed thereon passes through a dying unit and is recharged by a sub-charger. The images are transferred onto a transfer roller applied a negative voltage and then transferred onto the paper when a paper passes through between a transfer roller and a fixing roller.
