<p>PROBLEM TO BE SOLVED: To downsize a sheet processing apparatus having a function of folding a sheet using rollers.SOLUTION: The sheet processing apparatus includes: a first pair of conveying rollers R1 and a third pair of conveying rollers Rt2 that convey a sheet; a second pair of conveying rollers Rt1 that receives the sheet conveyed by the first pair of conveying rollers R1 and conveys the sheet downstream; and a branching claw that sets a first guiding position for guiding the sheet to the second pair of conveying rollers Rt1, a second guiding position for guiding a deflected portion of the sheet to the third pair of conveying rollers Rt2, and a third guiding position for guiding the sheet to the third pair of conveying rollers Rt2. The second pair of conveying rollers Rt1 is rotated backward in a state that the sheet is held by the first pair of conveying rollers R1 and the second pair of conveying rollers Rt1, to guide the deflected portion to the side of the third pair of conveying rollers Rt2 and cause the deflected portion to be folded by the third pair of conveying rollers Rt2.</p> |
