Filed: 1987-11-25
Abstract: PURPOSE:To always maintain the surface potential of an electrifying member in the potential being suitable for electrifying a body to be electrified by providing a means for equalizing roughly the surface potential of the electrifying member and the potential of an external applying power source to the electrifying member. CONSTITUTION:As for the inner layer 2b of an electrifying roller 2, for instance, that of 10<1>OMEGAm is used, and an outer layer 2c is selected so that the sum of resistance of the inner layer and the over layer in a nip part becomes equal to the resistance layer of a single layer. As a result, a current flowing through the electrifying roll becomes 0.6mA and an uneven electrification is obviated. However, when the resistance of the nip part and the capacitance are too large, a desired potential cannot be electrified to a photosensitive drum. Therefore, in case of an above-mentioned case, when the surface of the electrifying roll is returned to the same potential as an applying power source 3 at every one rotation by using a destaticizing brush 4, etc., the surface potential of the electrifying roll is returned surely to the potential level of the applying power source, whenever it passes through the destaticizing brush, therefore, the electrification capacity of the electrifying roll is not deteriorated and the photosensitive drum can always be electrified stably to a desired potential.
