Fuser control device, fuser control method and image forming apparatus

摘要

A fuser control device that controls a fuser that heats and fuses developer on a medium for an image formation on the medium includes the fuser including a heating member that rotates while contacting and heating the medium, and a rotation member that rotates and sandwiches the medium with the heating member; a heat supply part that supplies heat to the heating member; a temperature detection part that detects a temperature of the heating member; a heating controller that controls the heat supply part based on a detection result by the temperature detection part; and a rotation controller that controls a rotational speed of the heating member.

主权项

1. A fuser control device that controls a fuser that heats and fuses developer on a medium for an image formation on the medium, comprising:
the fuser including
a heating member that rotates while contacting and heating the medium, anda rotation member that rotates and sandwiches the medium with the heating member; a temperature detection part that detects a temperature of the rotation member; and a rotation controller that causes the heating member to rotate at a first rotational speed before an image formation process, wherein the rotation controller determines a second rotational speed based on the detected temperature before the image formation process, the rotation controller causes the heating member that is rotating at the first rotation speed to rotate at the second rotational speed before the image formation process, the rotation controller causes the heating member to rotate at a third rotational speed that is different from the first rotational speed during the image formation process, and the rotation controller determines the second rotational speed after an image expansion process.
