<p>PROBLEM TO BE SOLVED: To obtain an image forming device capable of realizing a one-point color printing function at a low cost. SOLUTION: An LED array head 206, guided by two guide rails 221, 222, is movable, in a main scan direction, keeping a constant distance from the surface of a photosensor 201. Both end parts of the LED array head 206 are fixed to both ends of a wire 230 spread across a space between drive pulleys 223, 224 arranged on both sides of the photosensor 201. The LED array head 206 is moved in the main scan direction by the drive pulley 223 to be driven by rotation of a motor 22. A sensor 226 for detecting the home position of the LED array head 206 is arranged on one of the sides of the photosensor 201. The LED array head 206 forms a latent image corresponding to a second color stamp print image at a specified position on the surface of the photosensor 201, after the formation of a latent image corresponding to a first color image on the surface of the photosensor 201 by an unillustrated laser beam.</p> |
