In the control of a cutting mechanism of a sheet processing apparatus, when rear end cut region of a sheet is finely cut and divided into predetermined fine-cutting unit length, if sheet conveying direction length of rearmost end divided region is equal to or more than minimum reference length corresponding to the distance between cutting position of the cutting mechanism and nipping position of a pair of first conveying rollers and is less than maximum reference length in which predetermined fine-cutting unit length is added to minimum reference length, upper and lower blades of the cutting mechanism are held opened immediately after the downstream edge of rearmost end divided region is cut and the pair of first conveying rollers are driven at limited conveying speed lower than normal conveying speed.
