Title:
CHARGING DEVICE
Document Type and Number:
Japanese Patent JP3224576
Kind Code:
B2
Abstract:
PURPOSE: To obtain a wireless charging device, which can prevent the overflow of the discharge current to members except for an electrostatic latent image supporter as a charge receiver and the generation of ozone, by forming a device with a semi-conductive sheet-shape electrode, supply electrodes provided so as to contact to the semi-conductive layer side of the semi-conductive sheetshape electrode, and a power source connected to the supply electrodes.
CONSTITUTION: Two supply electrodes 6a, 6b are provided so as to contact to the semi-conductive layer 1 side of an electrode 3, and the supply electrodes 6a, 6b are connected to a high voltage source 9. An electrode supporter 7, which is provided opposite to a photosensitive drum 8 with a predetermined space, maintains the shape of the electrode 3. Discharging high voltage is supplied to the supply electrodes 6a, 6b by the high voltage source 9, and the discharging high voltage is supplied to the semi-conductive layer 1 of the electrode 3 to generate the discharge between the semiconductive layer 1 and the photosensitive drum 8, and the photosensitive drum 8 is charged. The electrode 3 is wound up by a winding reel 5, and the electrode 3 opposite to the photosensitive drum 8 is always renewed.
