Fixing apparatus and image forming apparatus that maintain a pressing force between a contact member and a heat rotating member

An image forming apparatus comprising:

• (A) an image forming portion that forms a developer image on a recording medium;
• and
• (B) a fixing apparatus that includes:
• (a) a heating rotating member that generates heat when energized;
• (b) a pressure rotating member that forms a nip portion, together with the heating rotating member, in which a developer image, formed on a recording medium, is fixed to the recording medium while the recording medium is transported through the nip portion;
• (c) a contact member that comes into contact with and feeds power to the heating rotating member;
• (d) a contact holding member that holds the contact member so that the contact member presses against the heating rotating member, and that causes at least a portion of the contact member to elastically deform between the heating rotating member and the contact holding member;
• and
• (e) a displacement mechanism that displaces a relative position of the heating rotating member with respect to the pressure rotating member,
• wherein, when the heating rotating member is separated from the pressure rotating member by the displacement mechanism, an interval between a fulcrum, at which the contact holding member holds the contact member, and a contact point, at which the contact member comes into contact with the heating rotating member, does not increase, and
• wherein the fixing apparatus fixes developer image, formed on the recording medium by the image forming portion, on the recording medium.
