PURPOSE:To obtain the good image quality without generating fogging and color impurity by changing the exposure speed of an image forming exposure and the passing speed of a pressurized part of a photoreceptive sheet. CONSTITUTION:The photoreceptive sheet 3 is coated with a microcapsule which encloses a color forming substance composed of an image forming agent, namely, a colorless dyestuff, and a photocuring agent such as a photopolymerizable monomer, etc., and said photoreceptive sheet 3 is image-wisely exposed to selectively form a cured image. And then, in case that an image receiving sheet 12 coated with a developing material is laminated with the photoreceptive sheet 3, followed by pressurizing them, the passing speed of the pressurized part of the photoreceptive sheet makes faster than the exposure speed. Thus, even when the exposure speed of the image forming exposure is low, as the passing speed of the pressurized part is faster than the exposure speed, the generation of the fogging and the color impurity is reduced, and as the exposure speed is low, the deterioration of the image quality is prevented. |
