An electronic apparatus includes a first thermoelectric converter that converts thermal energy dissipated from a heat source into electrical energy, a second thermoelectric converter provided on a side of a low-temperature portion of the first thermoelectric converter and that converts electrical energy into thermal energy, and a power supply controller that controls supply of power to the second thermoelectric converter such that the low-temperature portion of the first thermoelectric converter is cooled or heated.

Electronic apparatus and image forming apparatus with thermoelectric converters

An ink-jet recorder is disclosed which has an arrangement of a plurality of heat-generating elements, drivers for driving the heat-generating elements, and a drive circuit for controlling the drivers according to image data, wherein the drive circuit includes; a split-block drive circuit that divides the plurality of heat-generating elements into a plurality of blocks, and drives the heat-generating elements on a block-by-block basis in a time-sharing manner, and a data retaining circuit for retaining print data; and the split-block drive circuit that; drives each of the blocks of the heat-generating elements at printing operations, using a pre-pulse during which ink is not squirted and a main pulse during which ink is squirted; and drives another group of heat-generating elements differing from the currently-driven group of heat-generating elements, during intervals between the pre-pulse and the main pulse.
