Abstract
A fusing apparatus allows a recording member to pass through between a heat member and a pressure member, to transport and heat the recording member, and thereby fuses a toner image on the recording member. The fusing apparatus includes a temperature detector for detecting a surface temperature of the heat member in a non-contact manner. A surface of the heat member is configured such that a region of the surface all around a cylindrical configuration that faces a temperature detection area of the temperature detector has a higher emissivity than other regions.
Claims12
A fusing apparatus comprising:
- a heat member including therein a heat source and having a cylindrical configuration;
- and a pressure member coming into contact with said heat member by pressure, and allowing a recording member to pass through between said heat member and said pressure member, to transport and heat said recording member, and thereby fusing a toner image on said recording member, wherein
- said fusing apparatus further comprises
- a temperature detector for detecting a surface temperature of said heat member in a non-contact manner, wherein
- a surface of said heat member is configured such that a region of the surface all around said cylindrical configuration that faces a temperature detection area of said temperature detector has a higher emissivity than other regions.
