Title:
BRUSH ELECTRIFYING DEVICE AND IMAGE FORMING APPARATUS
Document Type and Number:
Japanese Patent JP3667733
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce the occurrence of a white stripe due to irregular electrification peculiar to an image forming apparatus.
SOLUTION: The brush electrifying device provided in the image forming apparatus is constituted so that is performed simultaneously with electrification only on the upstream side from a brush 1 where the brush 1 abuts on the surface of a body to be electrified 7 first so as to remove the influence of projecting bristles on the upstream side from the brush 1 causing the occurrence of the white stripe. Namely, by intentionally radiating discharging light of a discharging lamp 12 arranged at the preceding stage of an electrification part even to the upstream part of the brush, the charge at the upstream part of the brush is eliminated. The brush 1 is constituted by flocking fibers on foundation 2 very densely and is ordinarily black, so that the discharging light of the lamp 12 does not enter inside the brush electrifier but excellently electrifies a part except the upstream side from the brush. Thus, since the irregular electrification on the upstream side from the brush is reduced, the influence of the projecting bristles on the upstream side from the brush causing the occurrence of the projecting bristles is removed and the occurrence of the white stripe is reduced.
