Image formation apparatus

Abstract

An image formation apparatus includes a dot formation element; a voltage signal generation circuit configured to generate a voltage signal by using an amplification circuit including a transistor, the voltage signal including a plurality of driving voltage pulses each thereof driving the dot formation element, and at least one temperature measurement voltage portion each thereof being provided between two successive ones of the driving voltage pulses; a temperature measurement control unit configured to measure a temperature of the transistor on the basis of the voltage signal; and a switch circuit configured to output the voltage signal to the dot formation element during a period when the transistor amplifies a signal corresponding to each of the driving voltage pulses, and output the voltage signal to the temperature measurement control unit during a period when the transistor amplifies a signal corresponding to each of the at least one temperature measurement voltage portion.
