AI Technical Summary

Problems solved by technology

[0012] When the folding reinforcing roller is about to rise to the end of the paper bundle, if the pressure of the folding reinforcing roller is too strong, the folding reinforcing roller may stop at the end of the paper bundle or damage the end of the paper bundle. occur
In addition, if the pressure of the folding reinforcement roller is strong, there will be a non-negligible impact sound when rising to the end of the paper bundle or when lowering to the outer area of ​​the paper bundle

Abstract

The invention provides a sheet folding apparatus, an image forming apparatus and a sheet folding method. The sheet folding apparatus includes a fold unit which folds a center of a sheet bundle to form a fold line, and a reinforce roller which moves along the fold line while applying pressure to the fold line to reinforce the fold line. The reinforce roller includes plural sub-rollers which are concentrically coupled to each other in a rotation axis direction, and the respective sub-rollers apply different pressures to the fold line.

Description
