ABSTRACT:
According to a first aspect of this invention, it is assumed that the recording is carried out on the recording medium by a non-catalyst-containing recording agent and a liquid-state catalyst is coated on the recording medium at the time of erasing processing and subsequently the heating and irradiation of near infrared rays are carried out as the erasing processing. Also, according to a second aspect of this invention, it is assumed that the recording is carried out on the recording medium by a catalyst-containing recording agent and, at the erasing processing time, the heating and irradiation of the recording agent are simultaneously carried out using a thermal emission and near IR irradiation source such as a halogen lamp.
