Classification: CPC G | IPC G

Claim 9:
10. A non-transitory recording medium storing instructions for a computer of an image forming system, wherein:
the image forming system comprises:
an image forming apparatus that comprises:
a transfer device that transfers a toner image onto a sheet; and
a fixing device that fixes the toner image transferred by the transfer device to the sheet;

a sheet heating device that heats the sheet on an upstream of the fixing device in a sheet conveyance direction;
an apparatus temperature detector that detects a temperature inside the image forming apparatus; and
an unheated-sheet temperature detector that detects a temperature of the sheet before the sheet heating device heats the sheet,

the instructions cause a computer of the image forming system to function as:
a controller that:
causes the sheet heating device to heat the sheet based on a detection result by the unheated-sheet temperature detector and a sheet passing condition of the sheet, and
corrects at least one of a transfer current and a transfer voltage in the transfer device based on a detection result by the apparatus temperature detector in a case where the sheet heating device heats the sheet,

the image forming system further comprises:
an ambient temperature detector that detects an ambient temperature outside or inside the image forming apparatus, and

the controller corrects at least one of the transfer current and the transfer voltage in the transfer device based on a difference between the detection result by the apparatus temperature detector and a detection result by the ambient temperature detector.
