PROBLEM TO BE SOLVED: To provide toner particles containing a plurality of microcapsules capable of forming a color image without complicated management of consumables, and a color image forming method and apparatus using the same. I do. SOLUTION: Microcapsules MCy, MCm, M having photoisomerizable substances having different photoresponsiveness on each capsule wall. Each of the internal phases of Cc includes a dye precursor 10 having a different color developing ability. a, 10b, 10c and an auxiliary substance 9 are arranged, and these microcapsules MCy, MCm, MCc, a developer 3 and an auxiliary substance 4, etc. are dispersed and mixed in the toner resin 2 to form full color particles FMCT. is there. After the electrostatic latent image formed on the photoreceptor 21 is developed using the full color particles FMCT, the first light capable of photoisomerizing the three types of photoisomerizable substances by the coloring light writing heads 27a, 27b, 27c, respectively. Lights R1a, R1b, and R1c are respectively radiated according to full-color recording data. After transferring the full-color particles FMCT to a sheet, the sheet is heated and fixed. |
