Abstract
A sheet folding unit, including: a first folding roller configured to rotate around a first axis; a second folding roller configured to rotate around a second axis which is in parallel with the first axis and biased to the first folding roller separably to a separating direction to make a nip together with the first folding roller therebetween; a blade configured to push a surface of a sheet into the nip; and a roller cover configured to move together with the second folding roller in the separating direction to prevent the second folding roller contacting the sheet when the blade unit starts contacting the sheet.
