Document Type and Number:
Japanese Patent JP6769062
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a charging member that suppresses the generation of fine colored lines when a photoreceptor is contact-charged by a charging member to which only a DC voltage is applied, and the generation of white spots when a photoreceptor is contact-charged by a charging member to which a voltage in which an AC voltage is superimposed on a DC voltage is applied.SOLUTION: There is provided a charging member comprising: a supporting member; a conductive elastic layer that is arranged on the supporting member; and a surface layer that is arranged on the conductive elastic layer, where irregularities having a period of less than 0.1 mm and irregularities having a period of 0.1 mm or more are distributed on the entire outer peripheral surface and satisfy the following requirements (1) and (2); the half-value width of the maximum frequency value in a height distribution of the outer peripheral surface is 1 μm or more and 3 μm or less. (1) The irregularities having a period of less than 0.1 mm has an average height of more than 0 μm and 4 μm or less. (2) The irregularities having a period of 0.1 mm or more has an average height of 5 μm or more and 30 μm or less.SELECTED DRAWING: Figure 1
