摘要： A developing roller includes a developing sleeve having a nonmagnetic material, and a magnet roll provided inside the developing sleeve and formed by dispersing a magnetic powder in a polymer compound. A portion of the magnet roll corresponding to a developing pole of the magnet roll is equipped with a main-pole molded magnet whose magnetic force per unit of volume is greater than that of the magnet roll. A magnetic pole adjacent to the developing pole of the magnet roll downstream in the developer conveyance direction has a peak magnetic flux density on the developing sleeve greater than that of the developing pole, and has a half value width, which is the width of the magnetic pole at which a magnetic flux density of one-half the peak magnetic flux density is exhibited, greater than that of the developing pole.

摘要： A developer-carrying member to transport a developer having a carrier to a developing area facing an image carrying member in an image forming apparatus includes a sleeve. The sleeve carries the developer. The surface of the sleeve has a maximum roughness Rmax of one-sixth or greater than a particle diameter of the carrier, and a surface index of 1.5 or greater. The surface index is expressed by the equation of “surface index=Rmax/(Ltotal-LL),” in which LL is a measurement-range length selected from a roughness profile of the surface of the sleeve, Ltotal is a total surface distance of the developer-carrying member in the measurement-range length LL, and Rmax is a maximum roughness of the sleeve surface, defined by a difference between a maximum roughness value and a minimum roughness value on a roughness profile of the surface of the sleeve.
