PURPOSE:To drastically extend the use number of times of an ink sheet and to always provide a stable image by eliminating possibility such that powder ink is also bonded to the bonding part of an ink layer or possibility such that image deterioration such as optical density irregularity or the reproducibility inferiority of an image line is generated in a formed image even when the reproduction/image formation of the ink sheet is repeated many times using powder ink. CONSTITUTION:Powder ink 11 is formed by externally adding carbon black 31 to the periphery of a matrix particle 21. Carbon black 31 is densely present in the vicinity of the surface of the matrix particle. |
