Abstract
An image forming apparatus having a fixing unit fixing a developer image formed based on image data received onto a medium includes a target fixing temperature determination unit, a fixable temperature range computing unit, and a fixing temperature control unit. The target fixing temperature determination unit determines fixing temperature arranged based on the medium as target fixing temperature. The fixable temperature range computing unit computes a fixing temperature range fixable the developer image on the medium by using medium information of the medium while using the target fixing temperature as reference temperature. The fixing temperature control unit controls the fixing unit based on the fixable temperature range computed by the fixable temperature range computing unit.
Claims30
An image forming apparatus comprising a fixing unit fixing a developer image formed based on received image data onto a medium, the image forming apparatus comprising:
- a target fixing temperature determination unit determining fixing temperature arranged based on the medium as target fixing temperature;
- a fixable temperature range computing unit computing a fixable temperature range to fix the developer image on the medium by using one or more temperature offset values selected based on medium information and the target fixing temperature;
- and
- a fixing temperature control unit controlling the fixing unit based on the fixable temperature range computed by the fixable temperature range computing unit,
- wherein the fixable temperature range includes the target fixing temperature, and the fixing temperature control unit starts to print when the temperature of the fixing unit is in the fixable temperature range and controls the temperature of the fixing unit such that the target fixing temperature is maintained,
- wherein the one or more temperature offset values differ according to the medium information.
An image forming system comprising:
- an image processing apparatus processing image data;
- and
- an image forming apparatus comprising a fixing unit fixing a developer image formed based on the image data received from the image processing apparatus onto a medium, the image forming apparatus comprising:
- a communication unit communicating with the image processing apparatus;
- a target fixing temperature determination unit determining fixing temperature arranged based on the medium as target fixing temperature;
- a fixable temperature range computing unit computing a fixable temperature range to fix the developer image on the medium by using one or more temperature offset values selected based on medium information and the target fixing temperature;
- and
- a fixing temperature control unit controlling the fixing unit based on the fixable temperature range computed by the fixable temperature range computing unit,
- wherein the fixable temperature range includes the target fixing temperature, and the fixing temperature control unit starts to print when the temperature of the fixing unit is in the fixable temperature range and controls the temperature of the fixing unit such that the target fixing temperature is maintained,
- wherein the one or more temperature offset values differ according to the medium information.
