The utility model relates to an imaging device which can improve open and close linkage with a protective cover and release the operability of the protective cover of the imaging device in a nip of a fuser unit. The imaging device comprises a linkage mechanism for the linkage of the protective cover and a pressure mechanism forming the nip of the fuser unit, wherein the linkage mechanism comprises a slide part which is in close and open linkage with the protective cover so as to slide and is provided with an abutted part, an arm which is provided with an arm abutted part abutted with a slide component, and a cam which rotates through rotating linkage with the arm, so that the pressure of the pressure mechanism is changed, when the pressure mechanism applies large force on the slide component directly or indirectly, the linkage mechanism is abutted with a surface forming a small angle with a moving direction, when the applied force is small, the linkage mechanism is abutted with a surface forming a large angle with the moving direction. |
