Description

FIELD This disclosure relates to the field of temperature control, and specifically to a fusing temperature control method, device, and image forming apparatus. BACKGROUND The fusing process of a laser printer fixes the toner image onto the paper through heating and pressure. This process is mainly carried out by the fuser, which uses a heating roller and a pressure roller to melt the toner and make it penetrate into the paper, thereby forming a permanent image on the paper. The heating temperature for fusing is usually above 150°C, and sometimes can reach 230°C or higher. In some scenarios, if the printer continuously performs printing jobs, a large amount of heat may accumulate inside the apparatus. If various components of the printer are in a high-temperature environment for a long time, their service life may be reduced. In some existing technologies, the printing speed is reduced to prevent the temperature from rising continuously, but this will lead to a decrease in the output efficiency of printing tasks.
