ABSTRACT:
There is an image recording apparatus using a thermal head for use in a facsimile apparatus or the like. This recording apparatus comprises: an input device to input a plurality of kinds of image data; a discriminating device to determine the kind of image which is inputted to the input device; a thermal head as a recording device to reproduce the image inputted to the input device; and a control unit to variably control the energy which is supplied to the thermal head in order to make constant the recording density of the thermal head in accordance with the kind of input image data. When the input image is a half tone image, the control unit increases the supply energy to the thermal head as compared with the case of a simple binary image. When the resolution of the input image is high, the control unit reduces the supply energy to the thermal head than that when the resolution is low. The supply energy is reduced in the case of a copy image than that in the case of a received image. With this apparatus, characters, image, or the like can be always recorded at a constant recording density irrespective of the kind of image or the operating mode of the apparatus.
