According to one embodiment, an image forming apparatus includes an image forming unit, plural rollers, and a roller supporting mechanism. The image forming unit forms an image on a sheet carried in a predetermined carrying direction and extends in an orthogonal direction that is orthogonal to the predetermined carrying direction. The plural rollers are arranged opposite the image forming unit with a carrying path of the sheet arranged in-between and are arranged in a plural number next to each other in the orthogonal direction. The roller supporting mechanism, while pressing the sheet toward the image forming unit, supports the plural rollers in such a way that each roller independently moves, between a carrying position where the sheet is carried in the carrying direction and a separation position where the sheet is separated from the image forming unit.
