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 5):
The magnet roller according to  claim 1 , wherein\n the plurality of magnetic poles include a peeling pole for peeling off a developer carried by the developing sleeve, and in the shape of the cross section of the magnet portion, a portion of the outer edge that corresponds to the peeling pole includes a straight portion.
