ABSTRACT:
A sheet post-processing apparatus includes a pair of folding rollers for folding a transported sheet stack by rotation while nipping the sheet stack, a pushing plate for pushing the transported sheet stack into the folding rollers by advancing and retreating relative to the folding rollers, a stack transport upper roller and a stack transport lower roller (first load device) for applying a load to the pushing plate in pushing the sheet stack by contacting the sheet stack at an upstream side of the folding rollers, and sheet holding mechanism (second load device) having a lever for applying a load to the pushing plate in pushing the sheet stack by contacting the sheet stack at the downstream side of the folding rollers. An image forming apparatus is equipped with the sheet post-processing apparatus.
