Fixing device and image forming apparatus

A fixing device that fixes an unfixed toner image formed on a recording material onto the recording material, comprising:

• a heating rotating member configured to be rotatable and to heat the unfixed toner image;
• a heater configured to heat the heating rotating member, provided on an inner peripheral surface of the heating rotating member.
• a pressing rotating member configured to be rotatable and to form a fixing nip portion by coming in contact with the heating rotating member;
• and
• a separating member configured to separate the recording material having passed through the fixing nip portion from the heating rotating member, the separating member being provided downstream of the fixing nip portion in a conveying direction of the recording material at the other side of the heating rotating member from the heater to be opposed to the heating rotating member with a gap in a non-contact state,
• wherein the pressing rotating member comes in contact with the heating rotating member to form the fixing nip portion that nips and conveys the recording material with a first pressure or a second pressure that is lower than the first pressure, and
• wherein the separating member moves more downstream in the conveying direction when the pressure of the fixing nip portion is the second pressure than when the pressure of the fixing nip portion is the first pressure.
