  • Magnetic Brush Developing In Electrophotography (AREA)

Abstract

PURPOSE: To obtain the good image of high image density free from any photographic fog by generating the magnetic field acting upon the magnetic toner between an electrostatic image holding body for visualized images and photographic fog removing means thereby removing the toner stuck on the nonimage part.
CONSTITUTION: An electric power source V1 for applying AC bias for readily performing toner transfer and for improving image quality is provided and an electrostatic image holding body 1 holding the sensible image rotates and moves to a photographic fog eliminating means 3. This photographic fog eliminating means 3 consits of a photographic fog removing roller. This roller 3 is constituted by a nonmagnetic sleeve connotating a magnet roller or magnet roll having magnetic poles and rotatable relatively with this, is insulated electrically from the other and is held in a floating state. Thereby, the good image of sufficiently high image density free from any photographic fog may be obtained.
