ABSTRACT:
There is provided a recording apparatus for recording onto a recording paper comprising: a recording head to record onto the recording paper, the recording head having plural heat generating elements; a temperature sensor to detect a temperature; and a controller to ON/OFF control the heat generation of the heat generating elements in accordance with the detected temperature on the basis of a temperature fluctuation prediction which has experientially and previously been obtained in accordance with recording conditions. The controller controls the heating operation of the heat generating elements by the temperature increase function and temperature decrease function. Thus, the temperature can be held to a value within a range suitable to print and the printing operation can be executed at a high speed.
