Abstract

PURPOSE:To prevent the dirt due to toner on a background section, by charging the toner and recording paper with the same polarity before the application of a picture signal. CONSTITUTION:A toner 2 is charged negative by applying a negative voltage 11 to a blade 3. When a recording paper 4 charged negative with a corotron 4 passes on a toner roller 1 holding the toner with magnetic force, a positive picture signal 10 is applied to a recording electrode 6. Although the toner attracred with a positive electric field of the electrode 6 is transposed on the paper 4, since the background of the recording paper 4 is charged negative, the toner charged negative does not attach to the paper 4. The paper 4 formed with a toner image is de-charged with a de-charger 7 and fixed with a fixing roller 9.
