摘要： A charging device includes a charging member disposed opposite to a surface of an image carrier. The image carrier is charged by applying a voltage to the charging member, and the charging member includes a substrate and a resistor layer thereon. The resistor layer is disposed with two spacers contacting with the image carrier, so that a gap is created between the image carrier and the resistor layer between the two spacers, wherein width variation of the gap with time is prevented. The end portions of the resistor layer of the charging member protrude above the resistor layer between them, and the spacers are constituted by protrudent fractions of the end portions of the resistor layer.

摘要： An intermediate image transfer type, tandem color image forming apparatus of the present invention includes four photoconductive drums assigned to black, yellow, magenta and cyan, respectively. In a black mode, the drums assigned to the colors other than black are released from an intermediate image transfer belt. As soon as the trailing edge of a black toner image is transferred to the intermediate image transfer belt, the above drums are again brought into contact with the belt. The drums and intermediate image transfer belt therefore wear little despite contact thereof and deteriorate little despite pressure acting therebetween.
