Abstract
A fixing device includes a radiating portion that radiates light on a recording medium on which a toner image is formed and that is transported along a transport path, a partition member that transmits the light radiated from the radiating portion and partitions between the radiating portion and the transport path, and a drive section that moves a scraping member scraping toner that adheres to the partition member and is heated by the radiation of the light from the radiating portion so as to contact a surface of the partition member of the transport path side.
Claims13
A fixing device comprising:
- a radiating portion that radiates light on a recording medium on which a toner image is formed and that is transported along a transport path;
- a partition member that transmits the light radiated from the radiating portion and partitions between the radiating portion and the transport path;
- and
- a drive section that moves a scraping member which scrapes toner that adheres to the partition member, the toner being heated by the radiation of the light from the radiating portion, wherein the scraping member contacts a transport path side surface of the partition member, the transport path side surface being a surface that faces the transport path,
- wherein the radiating portion radiates the light so that the temperature of the partition member is equal to or higher than a third temperature, and
- wherein the drive section moves the scraping member so as to scrape the toner when the temperature of the partition member is equal to or higher than the third temperature.

- a partition member that transmits the light radiated from the radiating portion and partitions between the radiating portion and the transport path;
- and
- a drive section that moves a scraping member which scrapes toner that adheres to the partition member, the toner being heated by the radiation of the light from the radiating portion, wherein the scraping member contacts a transport path side surface of the partition member, the transport path side surface being a surface that faces the transport path,
- wherein the radiating portion stops the radiation of the light when a temperature of the partition member is equal to or higher than a first temperature,
- wherein the drive section moves the scraping member so as to scrape the toner after the radiating portion stops the radiation of the light, and
- wherein the drive section moves the scraping member so as to start the scraping of the toner when the temperature of the partition member is equal to or lower than a second temperature that is lower than the first temperature.
