ABSTRACT:
A drive device for a heat sensitive recording head in which the heat generating elements in an entire array generate heat uniformly. The heat generating elements within an array-type heat sensitive recording head are separated into groups. Voltage dropping elements connect the various heat generating elements to common terminals, one of which is provided for each group. The voltage drops provided by the various voltage dropping elements are adjusted such that the heat generating elements produce heat uniformly so that the image recorded is uniform over the entire recording surface.
