Abstract

PURPOSE:To contrive to reduce the nonuniformity of the charge supply quantity by a simple constitution, by setting the width of the contact surface of a conductive brush to a prescribed value. CONSTITUTION:Width W in the moving direction of a formed body 1 of a conductive fiber 3a formed on a substrate 2 of a conductive brush 3 for abutting on an image forming body 1 is set so that the electrification time becomes >=0.1sec. According to this simple constitution, the nonuniformity of the charge supply quantity is suppressed, an image is formed without generating the contamination in a background part, and no uneven electrification is generated. In this regard, the conductive fiber is a pile fabric whose size is 2-20 deniers, and also, it is desirable that its fiber density is 50,000-200,000 fibers/inch<2> and fur length of the fiber is 2-10mm.
