Abstract
A sheet folding method has the first introduction process to introduce a sheet between the first rotary folding body and the first rotary pressure-contact body, and between the second rotary folding body and the second rotary pressure-contact body, respectively; the first folding process in which, under the condition that the first and second rotary folding bodies are in contact with the first and second rotary pressure-contact bodies, respectively, and rotated in the reversal direction to each other, thereby the conveying force of reversal directions to each other is acted and the sheet is bent and a fold is formed, and the fold of the sheet is conveyed between the first and second rotary folding bodies thereby the sheet is folded; the second introduction process to introduce the sheet folded by the first folding process using the similar structure to the first introduction process; and the second folding process using the similar steps to the first folding process.
