ABSTRACT:
A sheet folding apparatus includes: a fold roller pair which forms a nipping portion and inserts the center of a sheet bundle into the nipping portion to form a fold in the sheet bundle; a folding blade which moves from a standby position and presses the center of the sheet bundle against the nipping portion when the fold is formed, and returns to the standby position after the pressing of the nipping portion is completed; and a protection member which prevents an access to a front edge of the folding blade in a longitudinal direction of the front edge when the folding blade is located at the standby position.
