    摘要： An image forming apparatus has an image bearing member; and a charging member forming a nip with the image bearing member to charge the image bearing member. Conductive particles are provided in the nip and a time factor &agr; represented by a following equation satisfies a condition &agr;>15: &agr;=2&pgr;·k·Nc·(W/Vc)/(&rgr;·Cd·Z) Z=−0.5·1n(&pgr;·k·Nc)−1n({square root over (&bgr;)}·D/2) (&bgr;=1.1932) in which &rgr; (&OHgr;) represents a surface resistivity of said image bearing member; Cd (F/mm2) represents an electrostatic capacitance of the image bearing member; D (mm) represents a diameter of the conductive particle; Nc (particle/mm2) represents a density of the conductive particles present on the charging member; Vc (mm/sec) represents a surface moving speed of the charging member; Vd (mm/sec) represents a surface moving speed of the image bearing member; k=Vc/Vd; and W (mm) represents a width of the nip in the moving direction of the image bearing member.
