the rotating amount of the motor of the pressing roller 60 which is proportional to the traveling distance of the developing paper 52 the feed roller 82 122 can be equipped with a cooling mechanism to ensure that the surface temperature is below 75 u00b0 c in this case though the capacity of the cooling mechanism can be reduced compared to the case when the feed roller 82 122 is always contacting the heating roller 80 or the heater plate 120 the heating capacity of the heating roller 80 or the heater plate 120 is also reduced in the above embodiments the contacting mechanism is provided for the feeding device feed roller 82 122 alternatively the contacting mechanism may be provided for the heating device heating roller 80 heater plate 120 or for both the feeding device and the heating device the contacting mechanism is exemplified by the combination of springs 94 and a solenoid 96 in the above embodiment a combination of a motor and a cam or a hydraulic actuator cylinder can be employed as the contacting mechanism instead the image making process of the above embodiment is exemplified by the use of image transfer type photo pressure sensitive medium naturally the self developing type photo pressure sensitive medium can be employed in the above embodiment further such type of image medium may be employed that a photo sensitive resin in the microcapsules coated on the medium surface is softened by the exposure of light and the image is developed by pressing the microcapsules with a pressure roller obviously many modifications and variations of the present invention are possible in light of the.
