Abstract
A sheet processing apparatus includes a pair of squeezing members having a projection and a recess to engage each other, to squeeze a sheet bundle inserted therebetween in a direction of thickness of the sheet bundle, and a pressure applying unit to apply pressing force to the squeezing members to squeeze and bind the sheet bundle. The pressing force generated between the squeezing members by the pressure applying unit increases in strength as a relative distance between the squeezing members decreases.
