Abstract: A sheet folding device includes a folding path, a positioning member, a first folding roller, a second folding roller, a folding blade, a guide path, and a conveying roller. The positioning member is to support a leading edge of a sheet fed along the folding path and align the sheet at an initial folding position. The first folding roller is to engage with the second folding roller to form a folding nip. The folding blade is to move to an insertion position to push the sheet on the folding path into the folding nip. The guide path is provided around the first folding roller to return the sheet that has passed through the folding nip to the folding path. The conveying roller is to partially rotate around the first folding roller, to engage with the first folding roller to form a conveying nip and to feed the sheet along the guide path.
