Image forming apparatus

An image forming apparatus comprising:

• a heating rotating member configured to supply heat to a recording material;
• a pressurizing rotating member configured to pressurize the heating rotating member;
• a temperature control portion configured to control a temperature of the heating rotating member;
• an acquiring portion configured to acquire information regarding a basis weight of the recording material to which the toner image is fixed;
• and
• a control portion,
• wherein a toner image is fixed on the recording material by being supplied with heat and pressure by the heating rotating member and the pressurizing rotating member,
• wherein one mode can be performed among multiple modes including a first mode and a second mode in a mixed job in which multiple recording materials are mixed that include a first recording material with a first basis weight and a second recording material with a second basis weight that is less than the first basis weight,
• wherein when the first mode is set, the control portion performs such a control that a toner image is fixed to the recording material with the first basis weight and the recording material with the second basis weight at a common constant adjusted temperature on condition that the recording material with the first basis weight does not follow the recording material with the second basis weight, and
• wherein when the second mode is set, the control portion performs such a control that a toner image is fixed to the recording material with the first basis weight at a first temperature suitable for the first basis weight and a toner image is fixed to the recording material with the second basis weight at a second temperature suitable for the second basis weight.
