を講じる必要があった。Structure of the conventional example and its problems A typical example of the conventional transfer image forming method is the thermal transfer method. This uses a transfer image forming medium with a thermal transfer ink layer coated on a base, and a thermal head for applying thermal shock to this transfer image forming medium. By doing so, a required portion of the thermally transferable ink layer of the transfer image forming medium described in -1- is melted or sublimated,
It is intended to be transferred onto a printed matter. In this type of transfer method, the thermal head is energized and energized according to the image forming pattern.
Since the heating process is a process of directly transferring the thermal transfer ink onto the printed matter, for example, as two images are continuously formed, heat accumulates in the thermal head and the conditions for transfer image formation are disturbed, or Thermal sensitivity: Normally, multiple heating elements are used to form multiple pixels, but there are problems such as differences in transfer conditions between the multiple heating elements, and to prevent this, the image forming speed has to be increased. It was necessary to take special measures such as slowing down the heat to reduce heat accumulation in the thermal head or detecting the temperature of the thermal head to control the head heating conditions for image formation.
