ABSTRACT:
There is provided a sheet processing apparatus that is capable of allowing a decrease in the speed at which sheets are discharged to a stacking device even if sheets are conveyed into the sheet processing apparatus at short time intervals, or capable of eliminating the necessity of using an aligning device that can perform each alignment at a high speed, or capable of reducing the number of times of operations to be performed by the aligning device, and an image forming apparatus that is provided with the sheet processing apparatus. A plurality of sheets being conveyed is superposed. The sheets conveyed from the sheet superposing device are stacked. The sheets stacked in the stacking device are aligned. A sheet superposing device superposes a plurality of sheets being conveyed. A stacking device stacks thereon the sheets conveyed from said sheet superposing device are stacked. An aligning device aligns the sheets stacked in said stacking device. A controller that causes said sheet superposing device to perform a sheet superposing operation irrespective of a sheet bundle as a unit to be processed by the sheet processing apparatus.
