<P>PROBLEM TO BE SOLVED: To improve the quality of printing by efficiently controlling a substrate treating agent at an appropriate temperature in an apparatus and a method for treating a substrate and a printing machine. Ž<P>SOLUTION: A substrate treating agent feeding apparatus 44 includes a first substrate treating agent circulating line which can circulate and convey the substrate treating agent and can feed the substrate treating agent to a substrate treating agent feeding roll 42a, a heating apparatus (a temperature controlling means) 57 for controlling the temperature of the substrate treating agent circulated and conveyed in the first substrate treating agent circulating line in a preset temperature region, a defoaming means for removing bubbles generated with the substrate treating agent circulated and conveyed in the first substrate treating agent circulating line, and a substrate treating agent supplementing means for supplementing the substrate treating agent into the first substrate treating agent circulating line.
