A non-transitory computer-readable recording medium storing a program of a fixing device, the fixing device including:

• a fixing side member disposed on a fixing side of a recording medium on which a toner image is formed;
• a fixing belt wound around the fixing side member;
• a back side supporting member configured to form a fixing nip for conveying the recording medium in a tightly sandwiching manner in a state where the back side supporting member is in pressure contact with the fixing side member with the fixing belt therebetween;
• a heating roller configured to heat the fixing belt from inside, the heating roller being rotatable;
• and
• a first movement section configured to move the fixing side member between a first pressure contact position where the fixing side member is brought into pressure contact with the back side supporting member with the fixing belt therebetween, and a second pressure contact position where the fixing side member is brought into pressure contact with the heating roller, the program including instructions executable by the first movement section for:
• moving the fixing side member to the first pressure contact position to bring the fixing side member into pressure contact with the back side supporting member with the fixing belt therebetween in the printing operation, and
• moving the fixing side member to the second pressure contact position to bring the fixing side member into pressure contact with the heating roller when the printing operation is not performed.
