Image recording apparatus using the grating light valve

An image recording apparatus for recording an image on a recording medium by exposure comprising:

• a light source comprising a semiconductor laser;
• a grating light valve for modulating light from said light source;
• a holding member for holding said recording medium which is exposed to the modulated light from said light valve;
• a light shielding member for blocking undesired light;
• a temperature control member for controlling temperature of a refrigerant;
• a light-shield cooling member for removing heat generated by blocking said undesired light with said refrigerant;
• a light-source cooling member for cooling said light source with said refrigerant;
• and
• wherein said refrigerant from said temperature control member noes through said light-source cooling member and said light-shield cooling member in this order and is returned to said temperature control member.
