Abstract: In a method for determining a time-varying temperature of at least one temperature-critical component of an electrophotography apparatus, especially a laser printer, a laser fax device and/or as a laser copying machine, with the electrophotography apparatus being arranged to be operated in at least two operating modes (21 ― 27), it is proposed that during the operation of the electrophotography apparatus the time-varying temperature of the temperature-critical component is determined in temporally directly successive time intervals (3) in such a way that in substantially each of the time intervals (3) a temperature value (1) of the temperature-critical component is determined at the end (33) of said time interval (3) depending on the temperature value (1) of the temperature-critical component at the beginning (32) of said time interval (3), on an estimated ambient temperature value, and the on the operating mode of the operating modes (21 ― 27), in which operating mode the electrophotography apparatus is operated during said time interval (3), and that the temperature value (1) of the temperature-critical component and the estimated ambient temperature value are determined at the beginning (32) of the first time interval (31) of the time intervals (3).
