摘要： An image forming system includes an image forming apparatus including a fixing unit, a folding processing portion, and a pressure-bonding portion. A first recording material having a first basis weight is fixed at a first temperature by the fixing unit and then is pressure-bonded by the pressure-bonding portion after a lapse of a first period. A second recording material having a second basis weight is fixed at a second temperature by the fixing unit and then is pressure-bonded by the pressure-bonding portion after a lapse of a second period. The second basis weight is larger than the first basis weight. The second temperature is higher than the first temperature. The second period is longer than the first period.

摘要： An image forming system includes an image forming unit, a varnish coating unit, a reception unit, and a control unit. The image forming unit executes an image forming process of forming an image on types of recording media including a first type of recording medium with a coated layer and a second type of recording medium without a coated layer. The varnish coating unit executes a varnish coating process of varnish coating a recording medium on which an image is formed by the image forming unit. The reception unit receives a printing job from a user. The control unit controls the varnish coating unit. When the printing job received by the reception unit is a printing job for executing the varnish coating process on the second type of recording medium, the control unit controls the varnish coating unit to prevent the varnish coating unit from executing the varnish coating process.
