Abstract

A fixing device includes a pressing roller, a fixing belt to receive a rotation force transferred from the pressing roller and to rotate thereby, a nip forming member which is mounted inside the fixing belt, the nip forming member including a heat transmission unit formed thereon, and a heat source, which is mounted inside the nip forming member, to simultaneously apply heat to the nip forming member and to the fixing belt through the heat transmission unit.

Description

technical field [0001] The present general inventive concept relates to an image forming apparatus. More particularly, the present general inventive concept relates to a fixing device for fixing a toner image onto a printing medium and an image forming apparatus having the same. Background technique [0002] An image forming apparatus (for example, a printer, a copier, a scanner, a multifunction machine, etc.) includes a device for fixing a developer image (for example, a toner image) transferred to a sheet by a transfer device known to those skilled in the art. the fixing device. [0003] In order to meet the recent demand for high-speed image forming apparatuses, it is necessary to rapidly increase the temperature of the nip area so that the fixing device can reach the fixing temperature as soon as possible. In addition, thermal stability is required so that a fixing operation is performed while maintaining a constant temperature that is not affected by thermal disturban...
