ABSTRACT:
A temperature control system is employed in a electrophotographic printer for controlling the temperature of a heat roller. In the system, the temperature of the heat roller is kept in a predetermined range of an operable range when printing is executed, and kept in a predetermined range of a standby range, which is lower than the operable range, when printing is unexecuted. The temperature of the heat roller is controlled to be raised up to the upper limit of the operable range before it is changed to be in the standby range when printing is terminated.
