Beschreibung
Zusammenfassung:	A sheet processing apparatus (100) includes: first to third pairs of conveying members (R1; R1a, R1b: Rt2; R3, R4: Rt2; R3, R4); and a bifurcating claw (B) that moves to a first guiding position for guiding the sheet (P) to the second pair of conveying members (Rt1; R2, R3), a second guiding position for guiding a deflected portion of the sheet (P) to the third pair of conveying members (Rt2; R3, R4), and a third guiding position for guiding a leading end of the sheet (P) to the third pair of conveying members (Rt2; R3, R4). The second pair of conveying members (Rt1; R2, R3) is rotated backward in a state in which the sheet (P) is held by the first pair of conveying members (R1; R1a, R1b) and the second pair of conveying members (Rt1; R2, R3), to guide the deflected portion to the third pair of conveying members (Rt2; R3, R4) and cause the deflected portion to be folded by the third pair of conveying members (Rt2; R3, R4).
