A thermal printing apparatus is provided with a thermal printing section (22) for selectively heating a heatsensitive color developing printing medium coated with diazonium compound to form an image thereon, and a photo-fixing section (24) for illuminating the printing medium thermally printed with light to fix the image formed. In the photo-fixing section (24), the printing medium is illuminated with normal light, for example, light from a fluorescent lamp, and an amount of normal light is always detected. When the light amount is insufficient, the light amount is compensated for by lighting an auxiliary fluorescent lamp (120), increasing the lamp current, or the like. |
