Abstract
According to one example, an image forming apparatus includes a detection unit that detects temperature information on a temperature of a toner stored in a toner cartridge, an image forming unit that forms a toner image on a sheet with the toner supplied from the toner cartridge, a fixing unit that fixes the toner image formed on the sheet by the image forming unit, and a control unit that controls a fixing temperature in the fixing unit according to the temperature information detected by the detection unit and an accumulated time in which the temperature information is detected.
Claims20
An image forming apparatus, comprising:
- a detector that detects temperature information of a temperature of a toner stored in a toner cartridge;
- an image forming device that forms a toner image on a sheet with the toner supplied from the toner cartridge;
- a fixing unit that fixes the toner image formed on the sheet by the image forming device;
- and
- a controller that controls a fixing temperature in the fixing unit according to the temperature information having a longest accumulated time and an accumulated time from a combination of the temperature information detected by the detector and the accumulated time in which the temperature information is detected.
A toner cartridge for storing a toner, comprising:
- a non-transitory storage medium that stores characteristic information for correcting a fixing temperature when a toner image formed on a sheet is fixed by a toner supplied from the toner cartridge,
- wherein the characteristic information comprises information for correcting the fixing temperature according to temperature information having a longest accumulated time and an accumulated time from a combination of the temperature information detected by a detector and the accumulated time in which the temperature information is detected.
An image forming method, comprising:
- detecting temperature information of a temperature of a toner stored in a toner cartridge;
- forming a toner image on a sheet with the toner supplied from the toner cartridge;
- fixing the toner image formed on the sheet;
- and
- controlling a fixing temperature according to the temperature information having a longest accumulated time and the accumulated time from a combination of the temperature information detected and the accumulated time in which the temperature information is detected.
