Image forming apparatus and image forming method using a negative image
insulating pattern formed on an electroconductive substrate
摘要:
An image forming apparatus comprises: an electroconductive substrate; an electroconductive member disposed opposite to the electroconductive substrate; a plate-forming unit for forming an insulating pattern on the electroconductive substrate; a supplier for providing a recording material between the electroconductive substrate and the electroconductive member, the recording material being capable of changing its adhesiveness corresponding to the polarity of a voltage applied thereto; and a voltage source for applying a voltage between the electroconductive substrate and the electroconductive member.
