Patent ID: 7203443

Claim:
An apparatus which forms an image comprising: a recording medium carrying mechanism which carries a material to be transferred and permits fixing of a visualizing agent adhered selectively to an electrostatic image formed on a latent image bearing member, and which moves to a predetermined position together with a sliding mechanism; a recording medium heating unit which supplies a predetermined heat and pressure to the material to be transferred, to which the visualizing agent has been transferred, and the visualizing agent, respectively, and fixes the visualizing agent to the material to be transferred, the recording medium heating unit including a first member made of material in which an eddy current can be generated, a second member capable of supplying a predetermined pressure to the first member, and a magnetic field generating unit which generates a magnetic field to generate an eddy current in the first member, the recording medium heating unit being movable to a predetermined position; a magnetic field generating unit driving mechanism which supplies a predetermined high-frequency output to the magnetic field generating unit to enable the unit to generate a magnetic field; a commercial power supplying mechanism which supplies a predetermined power used by the magnetic field generating unit driving mechanism to supply the predetermined high-frequency output to the magnetic field generating unit; an electrical connection mechanism which interrupts the power from the commercial power supplying mechanism to the magnetic field generating unit driving mechanism, between the commercial power supplying mechanism and the magnetic field generating unit driving mechanism; and a cover member which covers the magnetic field generating unit mechanism, the cover member being openable only when the recording medium carrying mechanism moves to a predetermined area, and while the cover member is being opened and protruded in a direction in which the recording medium heating unit slides, the recording medium carrying mechanism cannot return to the original position, the recording medium carrying mechanism movable in an opening direction of the cover member, wherein sliding of the recording medium carrying mechanism is restricted while the cover member is being opened.
