    摘要： A development magnet roller for use in a development roller of an electrophotographic image forming apparatus is provided. The development magnet roller has a development pole to form a magnetic field causing a developer born on a surface of the development roller including the development magnet roller to rise in a form of a series of ears in a development area of the image forming apparatus where the development roller opposes an image bearing member, and in a magnetic flux density distribution in a normal line direction of the development pole, a peak magnetic flux density is 120 mT or greater, a zero gauss region width is 70° or greater, and a half-value region width is 40° or smaller.

    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： Disclosed is an acrylic copolymer type of cissing inhibitor effective in restraining both of self-cissing and oil cissing. The cissing inhibitor for the cationic electrodeposition coating compositions is a polymer having a number-average molecular weight of 1000 to 50000 obtained by polymerizing a monomer mixture containing (A) a polymerizable unsaturated group-containing monomer having a chain hydrocarbon group with a carbon number of 6 or more and (B) a polymerizable unsaturated group-containing monomer having an amino group, characterized in that the amount of the polymerizable unsaturated group-containing monomer (A) occupied in the above-mentioned monomer mixture is 20% by mass or more, the total amount of the above-mentioned polymerizable unsaturated group-containing monomer (A) and polymerizable unsaturated group-containing monomer (B) is 40% by mass or more and the amount of the above-mentioned polymerizable unsaturated group-containing monomer (B) is larger than that of the above-mentioned polymerizable unsaturated group-containing monomer (A).

    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.
