ABSTRACT:
A disclosed fixing device includes a fixing member configured to heat and melt a toner image to fix it onto a recording medium; a pressure member abutting the fixing member to form a nip into which the recording medium is fed; a separating member disposed on the downstream side in the moving direction of the fixing member in relation to the nip in a manner to oppose the fixing member, and configured to perform a separating operation to prevent the recording medium from winding around the fixing member; an electrically grounded frame supporting the fixing member, the pressure member and the separating member; and a conductive member inserted between a supporting portion of the frame and a supported portion of the separating member and having a higher electric resistance than the frame. The separating member and the frame are rendered electrically conductive to each other only via the conductive member.
