PROBLEM TO BE SOLVED: To obtain an image forming device having such unit structure that an LED and a pressure developing means can be easily exchanged and using a photosensitive recording medium. SOLUTION: A photosensitive and pressure sensitive printer 40 is provided with a light shielding cassette 41 housing the photosensitive recording medium 1 where a microcapsule including a dye precursor and developer are mixed and applied and on which a latent image is formed based on the difference of mechanical strength by exposure. Then, the cassette 41 is integrally provided with an exposure and developing unit 43. Besides, the LEDs 32, 33 and 34 and the pressure developing means 35 shaped like a ball-point pen are concentrically arranged at the surface of the disk 31 of the unit 43 opposed to the medium 1. When all of the media 1 are used up, the cassette 41 is exchanged together with the unit 43. Besides, the LEDs 32, 33 and 34 and the developing means 35 are always exchanged for new ones in a fixed using time. Thus, trouble is prevented from occurring. |
