PURPOSE:To prevent an excess load from being brought to bear on heat generating parts by allowing a broad heating area to be secured even when the heat generating parts are arranged at a narrow interval, and also allowing a sufficient amount of heat to be obtained across the entire heating area even when a drive energy to a single heat generating part is decreased. CONSTITUTION:A thermal signal application means 4 is composed of a means 4 to apply a heat signal corresponding to image information to an ink 3 unit area, a means 6 to form an electrostatic field extending from an ink 3 surface to a recording sheet 5 side, synchronously with the application timing of the heat signal, a plurality of heat generating parts 21 which are arranged per pixel density when the heated ink 3 unit area is jumped to the recording sheet 5 side by an attraction force based on the electrostatic field by an electrostatic formation means 6, and a heating control part 30 which heats a plurality of heat generating parts 21 adjoining to the corresponding ink 3 unit area when a single image information is recorded. Subsequently, it is possible to secure a broad heating area even for heating parts arranged at a narrow interval and thereby set heat energy from a single heat generating part 21 to a small level when a prearranged mount of heat is sought. |
