Image-forming system

摘要

An image-forming system has an image-forming substrate that includes a base sheet, and a layer of microcapsules, coated over the base sheet, containing a plurality of at least one type of microcapsules filled with an ink. When a dot area of the layer of microcapsules is subjected to a pressure in a predetermined pressure range at a temperature in a predetermined temperature range, at least a portion of the plurality of at least one type of microcapsules, included in the dot area, are squashed and broken, thereby causing discharge of the dye from the squashed and broken microcapsules. A thermal printer includes a roller platen for exerting the pressure on the dot area, a thermal head for applying a thermal energy to the dot area to heat the same to the predetermined temperature, and a regulator that regulates a degree of application of the thermal energy to the dot area, thereby enabling a variation in the density of the discharge of the dye at the dot area to be obtainable.
