Abstract: A fixing device is equipped with a lower pressure roller, an upper pressure roller and a fixing belt which fix a toner image onto a sheet, by holding and conveying the sheet by a nip portion, and a control unit which controls rotation of the lower pressure roller. The control unit periodically changes a velocity of rotational drive of the lower pressure roller, at a frequency of which a period is shorter than a time needed for the sheet to pass through the nip portion, when the sheet passes through the nip portion.

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.
