An approach for forming a multi-colored image on a substrate that includes a thermochromic material capable of producing at least two different colors is disclosed. Individually selected pixels of the thermochromic material that correspond to the image are heated to predetermined temperatures. Each predetermined temperature corresponds to a predetermined color shift of the thermochromic material. While the individually selected pixels are being heated, an area that includes the individually selected pixels is flooded with an amount of UV radiation sufficient to at least partially polymerize the thermochromic material. A color of each individually selected pixel is determined by a predetermined temperature to which the pixel is heated and the amount of UV radiation to which the pixel is exposed.

An image recording device includes a laser irradiation device that emits laser lights output from a plurality of laser light emitting elements to different positions in a predetermined direction; and an image recording unit that controls the laser irradiation device to irradiate a recording object moving relative to the laser irradiation device in a direction different from the predetermined direction with laser so as to heat the object, form image dots, and record an image. The image recording unit controls the laser irradiation device, conducts recording such that at least one of the image dots, recorded alongside at different positions in a direction perpendicular to a relative moving direction of the object, is shifted relative to other ones of the image dots in the relative moving direction, and records a solid image on the object such that the image dot is partially overlapped with all adjacent image dots.
