  • Patent number: 12181818
    Abstract: Selecting one conveyance mode from a plurality of conveyance modes includes a first selection process of selecting the one conveyance mode based on a detection temperature of a temperature sensor from a first time point at which rotation of a fixing rotator is started to a second time point at which a particular period elapses from the first time point. The first selection process includes: determining whether an initial temperature is higher than or equal to a first temperature, the initial temperature being a detection temperature of the temperature sensor when a print instruction is received; in response to determining that the initial temperature is lower than the first temperature, setting the particular period to a first period; and in response to determining that the initial temperature is higher than or equal to the first temperature, setting the particular period to a second period longer than the first period.
