A color image forming method and apparatus using larger microcapsules each of which contains a plurality of kinds of smaller microcapsules scattered within the larger microcapsule, reacting substances that are mixed with each other to perform a coloring reaction being scattered inside and outside the smaller microcapsule. A protective wall of each smaller microcapsule is broken with a corresponding predetermined ultrasonic stimulus depending upon color component information to thereby cause the reacting substances to diffuse with each other to perform a coloring reaction and hence image printing. The conditions for breaking the protective walls of the respective smaller microcapsules that contain a color former component vary from smaller microcapsule to smaller microcapsule, or are determined depending upon the outer shapes, materials and thickness of the protective walls of the smaller microcapsules.
A color image forming method using microcapsule toner which includes a plurality of larger microcapsules each of which contains a plurality of kinds of smaller microcapsules dispersed therein, the plurality of kinds of smaller microcapsules being different in at least one of outer diameter, shell thickness and material so as to be broken by ultrasonic waves of different resonant frequencies respectively, each smaller microcapsule containing an air bubble and having a protective wall breakable with an ultrasonic wave of a corresponding predetermined resonant frequency, each smaller microcapsule containing inside its protective wall one of two reacting substances that react with each other when mixed to thereby cause a coloring reaction and the other of the two reacting substances being disposed outside the protective wall, the method comprising the steps of:
