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

A printing apparatus comprising:

• a toner cartridge for storing toners;
• a photoconductor drum for transferring the toners from the toner cartridge to a printing media;
• and
• a fusing device for fusing 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 inside the heat insulating component, an opening being formed on a side of the heat insulating component adjacent to the driving roller and communicated with the accommodating space;
• a heating component located inside the accommodating space and for generating heat;
• a heat conductive component connected to the heat insulating component and covering the opening;
• a heat reflecting component located inside the accommodating space and separated from the heat conductive component, the heat reflecting component comprising a reflecting portion, a cross section of the reflecting portion being formed in a conic section substantially, the reflecting portion being located on a side of the heating component away from the heat conductive component and for reflecting the heat generated by the heating component to the heat conductive component;
• and
• a fusing component movably surrounding the heat conductive component and the heat insulating component, the heat conductive component transferring the heat to the fusing component, the fusing component contacting with the printing media to fuse the toners onto the printing media when the driving roller drives the printing media to move along the moving direction.
