Abstract
According to one embodiment, a sheet binding apparatus includes a first roller, a second roller, and a nip-pressure adjusting section. The first roller attaches a tape to an edge portion of a sheet bundle. The second roller is opposed to the first roller in the sheet bundle thickness direction. The nip-pressure adjusting section is capable of adjusting, on the basis of the position of an edge portion leading end of the sheet bundle, a pressing force of a nip formed by the first roller and the second roller. Before the sheet bundle is inserted between the first roller and the second roller, an interval between the first roller and the second roller is equal to or smaller than the thickness of the sheet bundle.
