CORONA DISCHARGE DEVICE, METHOD OF ELECTRIFICATION AND IMAGE FORMING DEVICE

摘要

PROBLEM TO BE SOLVED: To solve such a problem as unevenness in image caused by lowering of the electrified amount at a low temperature when used in an electrophotographic device because the discharging characteristic of a di-corotron discharge device is influenced by the environmental temperature. SOLUTION: In the device, the temperature inside the corona discharging space is maintained constant by providing a temperature raising means by which the temperature in the corona discharging space is risen.
