Abstract: A sheet feeding device has a mounting portion allowing a stack of sheets to be mounted in a top-bottom direction, a suction/transportation portion provided above the mounting portion for attracting a first sheet positioned on top of the stack, and a blowing portion for blowing air to a foremost edge of the first sheet in a transportation direction while the first sheet is being attracted by the suction/transportation portion, thereby separating the first sheet from a second sheet next to the first sheet. After the first sheet is separated from the second sheet, the suction/transportation portion transports the first sheet in the transportation direction. The suction/transportation portion sets a suction force applied to the foremost edge of the first sheet smaller when the blowing portion blows air to the first sheet than when the suction/transportation portion transports the first sheet.

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.
