Abstract
A sheet-bundle spine treatment apparatus includes upper and lower press-rollers for adjusting a crease shape by moving while pinching front and rear surfaces of a spine of a folded sheet-bundle therebetween and a flattening roller for flattening a back of the sheet-bundle by moving while pushing the back of the spine of the sheet-bundle. At least one of the upper and lower press-rollers and the flattening roller is selected so as to allow it to operate.
Claims16
An image-forming apparatus comprising:
- an image-forming portion configured to form images on a sheet;
- and
- a sheet-bundle treatment apparatus configured to fold the sheet having the images formed by the image-forming portion in bundles and treats a spine of the folded sheet-bundle, the sheet-bundle treatment apparatus including:
- a crease treatment unit configured to press a crease of a folded sheet-bundle while moving along a spine of the sheet-bundle in order to perform a spine crease treatment for fortifying the crease of the folded sheet-bundle;
- a back treatment unit configured to push a back of the spine of the folded sheet-bundle while moving along the spine of the sheet-bundle in order to perform a flattening treatment for flattening the back of the spine of the sheet-bundle;
- and
- a selection portion facilitating selecting operation of at least one of the crease treatment unit and the back treatment unit.
