Abstract
An image forming unit forms a user image and a bonding image formed in a binding margin of a booklet and is for bonding a plurality of sheets forming the booklet. A bonding unit bonds the plurality of sheets by applying heat and pressure to the binding margin of the plurality of sheets. The image forming unit forms the bonding image and forms the user image at a first density on a sheet that satisfies a condition for enabling bonding in the bonding unit from among the plurality of sheets. The image forming unit forms the user image and does not form the bonding image or forms the bonding image at a second density lower than the first density on a sheet that does not satisfy the condition for enabling bonding from among the plurality of sheets.
Claims21
An image forming system comprising:
- an image forming unit configured to form a user image and a bonding image formed in a binding margin of a booklet and is for bonding a plurality of sheets forming the booklet;
- and
- a bonding unit configured to bond the plurality of sheets by applying heat and pressure to the binding margin of the plurality of sheets,
- wherein the image forming unit forms the user image and forms the bonding image at a first density on a sheet that satisfies a condition for enabling bonding from among the plurality of sheets, and
- wherein the image forming unit forms the user image and does not form the bonding image or forms the bonding image at a second density lower than the first density on a sheet that does not satisfy the condition for enabling bonding from among the plurality of sheets.
An image forming apparatus comprising:
- an image forming unit configured to form a user image arbitrarily prepared by a user and a bonding image that is formed in a binding margin of a booklet and is for bonding a plurality of sheets forming the booklet;
- and
- a discharge roller configured to discharge the plurality of sheets to a post-processing apparatus including a bonding unit configured to bond the plurality of sheets discharged by the discharge roller by applying heat and pressure to the binding margin of the plurality of sheets,
- wherein the image forming unit forms the user image and forms the bonding image at a first density on a sheet that satisfies a condition for enabling bonding from among the plurality of sheets, and
- the image forming unit forms the user image and does not form the bonding image or forms the bonding image at a second density lower than the first density on a sheet that does not satisfy the condition for enabling bonding from among the plurality of sheets.
An image forming system comprising:
- an image forming apparatus configured to form a user image and a bonding image formed in a binding margin of a booklet and is for bonding a plurality of sheets forming the booklet;
- and
- a post-processing apparatus including a bonding unit configured to bond the plurality of sheets conveyed from the image forming apparatus by applying heat and pressure to the binding margin of the plurality of sheets;
- and
- a controller configured to determine that there is an error when a sheet that does not satisfy a condition for enabling bonding in the bonding unit is included in the plurality of sheets,
- wherein in a case where the controller does not determine that there is an error, the image forming apparatus forms the user image and forms the bonding image at a first density, and
- wherein in a case where the controller determines that there is an error, the image forming apparatus forms the user image and does not form the bonding image or forms the bonding image at a second density lower than the first density.
