To provide a thermal recording medium, which can realize easy maintenance, does not produce wastes such as cartridges, and can realize easy control of recording sheets, and an apparatus and method for image formation. [MEANS FOR SOLVING PROBLEMS]A high-temperature color development capsule (23), a low-temperature color development capsule (27), and a low-temperature color development suppression capsule (28) are incorporated in a recording sheet (10). In a printer, the low-temperature color development capsule (27) is subjected to low-temperature color development and is then pressed to break the low-temperature color development suppression capsule (28), whereby low-temperature color development is fixed. Thereafter, the high-temperature color development capsule (23) is subjected to high-temperature color development.
