Fixing device and image forming device

A fixing device comprising:

• a fixing rotating member having a fixing surface with which a recording medium holding an unfixed image comes into contact;
• a pressing rotating member pressed to the fixing surface of the fixing rotating member to form a fixing process part between the pressing rotating member and the fixing surface through which the recording medium to pass;
• a displacing mechanism that can displace the pressing rotating member at least at a first setting position that the pressing rotating member pressed to the fixing surface is located in a first position relative to the fixing rotating member and at a second setting position that the pressing rotating member pressed to the fixing surface is in a second position shifted from the first position in the downstream side or the upstream side of a passing direction of the recording medium at the fixing process part;
• a guide member having a guide part that guides the recording medium to an introducing portion of the fixing process part between the fixing rotating member and the pressing rotating member;
• an adjusting mechanism that can adjust the position of the guide member in accordance with the displacement of the pressing rotating member at least to the first setting position or the second setting position by the displacing mechanism, wherein the adjusting mechanism adjusts an end of the guide part in the guide member near to the fixing process part to be located in a first state in which the end of the guide part is located at a position closer to the fixing surface of the fixing rotating member than to the surface of the pressing rotating member and a prescribed space separated from the introducing area of the fixing process part or in a second state in which the end of the guide part is located at a position closer to the surface of the pressing rotating member than to the fixing surface of fixing rotating member and nearer to the introducing portion of the fixing process part than in the first state.
