Abstract

PURPOSE:To perform stable electrification, by setting a current that flows on a conductive fiber decided by the resistance value of the conductive fiber and an impression voltage on a conductive brush electrifying device less than a limiting current by which the conductive fiber is burned. CONSTITUTION:The resistance value Rb or the impression voltage Va are decided so that a current value I that flows on the conductive fiber 3a decided by the resistance value Rb of the conductive fiber 3a and the impression voltage Va from a high voltage source 4 to the conductive fiber 3a can be set less than the limiting current by which the conductive fiber 3a is burned. Therefore, since the current I that flows on the fiber 3a is limited by the resistance value Rb of the conductive fiber 3a itself even when the conductive fiber is brought into contact with a photosensitive substrate 11, burning due to short-circuiting is prevent from being generated. in such a way, it is possible to prevent a photosensitive material from being damaged, thereby, stable recording can be performed.
