Image forming process and system, including heating step or device for increased density of images

A recording system for forming images on a recording sheet, comprising:

• an exposing device for image-wise exposing a pressure-sensitive photosensitive sheet to a radiation, so as to form thereon latent images, according to source image information provided on an original which has an image-bearing surface;
• a developing device for causing a chemical reaction to develop said latent images on said photosensitive sheet into visible images on a recording sheet;
• a feeding device for feeding said recording sheet;
• a detector for sensing a glossiness level of said image-bearing surface of said original;
• a heating device for heating the developed recording sheet for promoting said chemical reaction to thereby increase a density of said visible images;
• and
• a control device responsive to said detector, and operable for controlling at least one of a heating temperature of said heating device and a rate of feeding of said recording sheet by said feeding device, so as to give said recording sheet a glossiness corresponding to said glossiness level sensed by said detector.

• said heating device including a heat-generating source having a cylindrical wall, and a non-metallic heat-conductive endless belt in direct contact with said cylindrical wall for conducting heat generating by said source to said recording sheet, said cylindrical wall and said endless belt being rotated in the same direction and at the same rate as said recording sheet while said recording sheet is moved by said feeding device;
• a temperature sensor disposed on one of opposite sides of said non-metallic layer which is nearer to said heat-generating source;
• and
• a control circuit connected to said temperature sensor and said heat-generating source, for controlling said heat-generating source to regulate an amount of heat generated by said heat-generating source, according to an output signal provided by said temperature sensor.
