Abstract:
A magnet roller includes a magnet portion for generating magnetic force such that a plurality of peaks are formed in a magnetic force distribution. The magnet portion includes a plurality of magnetic poles. A cross section of the magnet portion includes a portion in which a distance from an axial center of the magnet portion to an outer edge of the magnet portion continuously changes in the circumferential direction. The magnetic force on a surface of a developing sleeve at a position corresponding to each of the plurality of magnetic poles is determined by (i) a distance from each of the plurality of magnetic poles to the developing sleeve in a radial direction of the developing sleeve and (ii) a magnitude of magnetic force in each of the plurality of magnetic poles. The distances from the plurality of magnetic poles to the developing sleeve in the radial direction are different.

Claim (Index 1):
A magnet roller disposed inside a developing sleeve formed in a cylindrical shape, the magnet roller comprising:\n a magnet portion for generating magnetic force such that a plurality of peaks are formed in a magnetic force distribution in a circumferential direction of the magnet roller, the magnet portion including a plurality of magnetic poles that are arranged in the circumferential direction so as to form the plurality of peaks, the magnet portion having a cross section that is orthogonal to an axis direction of the magnet roller, the cross section having a shape that is formed to include a portion in which a distance from an axial center of the magnet portion to an outer edge of the magnet portion changes continuously in the circumferential direction, wherein magnetic force on a surface of the developing sleeve at a position corresponding to each of the plurality of magnetic poles is determined by (i) a distance from each of the plurality of magnetic poles to the developing sleeve in a radial direction of the developing sleeve, and (ii) a magnitude of magnetic force in each of the plurality of magnetic poles, and distances from the plurality of magnetic poles to the developing sleeve in the radial direction of the developing sleeve are different.
