Fixing device and image forming apparatus

An image forming apparatus, comprising:

• a controller configured to control execution of a job;
• an image forming unit configured to form an image on a recording material;
• a fixing device configured to apply heat and pressure at a nip portion to fix a toner image to the recording material;
• wherein the fixing device comprises:
• a heating rotating member configured to be rotatable and apply heat to a recording material;
• a pressure rotating member configured to abut on the heating rotating member, be rotatable, and form the nip portion together with the heating rotating member;
• and
• a moving unit configured to move at least one of the heating rotating member and the pressure rotating member to an abutment position at which the nip portion is formed and a separation position at which the heating rotating member and the pressure rotating member are separated from each other,
• wherein the controller executes a job of forming images on the recording material in one mode out of a plurality of modes including a first mode and a second mode, a time moving from the separation position to the abutment position in a case where the image formation is performed in the first mode is a first time, a time moving from the separation position to the abutment position in a case where the image formation is performed in the second mode is a second time, and the first time is shorter than the second time.
