Title:
IMAGE FORMING DEVICE
Document Type and Number:
Japanese Patent JP3036939
Kind Code:
B2
Abstract:
PURPOSE: To reduce the influences of the defect, etc., of a photosensitive drum, and to form an image by setting the surface layer of a contact electrifying system electrifying member at a prescribed resistance value.
CONSTITUTION: The surface layer 5a of the contact electrifying system electrifying member 5 is formed in such a manner that a low-resistance conductive pigment and a high-resistance conductive pigment are mixed in binder resin. Thus, such phenomenum as that only a conductive pigment flocculates in the binder resin so that the resistance distribution of the surface layer is made uniform, and its resistance value becomes the prescribed one.
