PROBLEM TO BE SOLVED: To reduce nonuniformity of the density of an image to be formed. SOLUTION: In the case the uniformity of the density of an image to be formed is taken into much account, nonuniformity reduction mode information is inputted to a controller 30 from a mode judgement device 32, and control is exerted by the controller 30 such that a current which is applied to the discharge wire 2a of a scorotron electrifier 2 is greater than that which is applied for normal image-formation. Thus, even in the case the original document whose image is inputted is a photograph original-document, a halftone original- document or the like, nonuniformity of the image to be formed can be reduced. |
