Title: Electrophotographic recorder
Inventor: TANAKA TATSUO
IPC: G03G21/00
Filed: 1989-02-17
Abstract: PURPOSE:To improve printing quality by controlling such that a change in the conductivity of a brush is compensated according to an operational ambient temperature and a potential is imparted. CONSTITUTION:A photosensitive body 1 is electrified by an electrifier 3, and a scanning mechanism scans the surface of the photosensitive body 1 with light from a light source 2 to form a latent image. Toner electrically attracted to the surface of the photosensitive body 1 is transferred to a transfer material 6 by a transfer mechanism 5. After that, the toner remaining on the surface of an image carrier is removed by a cleaning device consisting of a conductive brush 7, a temperature sensor 9 detecting a temperature around the photosensitive body 1, and a power source 8 provided with a control mechanism. A potential with opposite polarity from a developer is imparted to the brush 7, and is controlled according to an ambient temperature. Thus, cleaning performance is not affected by a temperature, nor influences the surface, and therefore satisfactory printing quality can be maintained.
