摘要： An image forming apparatus includes a transfer belt, a pressure receiving roller, a secondary transfer roller, and a belt movement restricting section. The belt movement restricting section is disposed close to the back of the belt. When pressing the belt between the pressure receiving roller and the secondary transfer roller, and nipping paper between the belt and the secondary transfer roller, an angle defined by the portion, upstream from the secondary transfer roller, of the belt and an imaginary line connecting the pressure-receiving-roller axis with the secondary-transfer-roller axis is less than 90 degrees. During non-secondary-transfer mode, the belt movement restricting section is separated from the belt. During secondary transfer, the belt movement restricting section holds the belt not to let the belt pushed by the paper move toward the pressure receiving roller.
