摘要： A sheet feeding device includes a sheet feeding portion, a side end regulating portion, a feeding portion, first and second feeding roller pairs, an abutment member, an obliquely feeding roller pair, and first and second contact-and-separation mechanisms. Feeding of a long sheet is stopped after the sheet is fed to an upstream side of the second feeding roller pair by the feeding portion, and then is resumed in a state in which the first feeding roller pair is changed from a separated state to a feedable state and in a state in which the obliquely feeding roller pair is put in a separated state, and then the sheet is fed to the second feeding roller pair. A short sheet fed by the first feeding roller pair is obliquely fed by the obliquely feeding roller pair and then is fed to the second feeding roller pair.
