Fusing device adapted for fusing toners on a printing media and printing apparatus therewith

A printing apparatus comprising:

• a toner cartridge storing toners;
• a photoconductive drum for transferring the toners from the toner cartridge to a printing media;
• and
• a fusing device for fusing the toners onto the printing media, the fusing device comprising:
• a driving roller for driving the printing media to move along a moving direction;
• and
• a fusing unit comprising:
• a heat insulating component, an accommodating space being formed in the heat insulating component, an opening being formed on a side of the heat insulating component near the driving roller and communicated with the accommodating space;
• a heat generating component located inside the accommodating space and for generating heat;
• a heat conducting component connected to the heat insulating component and covering the opening;
• a heat reflecting component connected to the heat insulating component, the heat reflecting component being located inside the accommodating space and on a side of the heat generating component away from the heat conducting component for reflecting the heat generated by the heat generating component to the heat conducting component;
• a metal reinforcing component installed on an outer side of the heat insulating component, a stiffness of the metal reinforcing component being greater than a stiffness of the heat insulating component;
• and
• a fusing component movably enclosing the heat conducting component, the heat insulating component and the metal reinforcing component, the heat conducting component conducting the heat to the fusing component, and the fusing component contacting with the printing media to fuse the toners onto the printing media by heating when the driving roller drives the printing media to move along the moving direction.
