TONER FUSER FOR FUSING TONERS ON A PRINT MEDIUM AND RELATED LASER PRINTER

摘要

A toner fuser includes a pressure roller for pressing toners on a print medium so as to fuse the toners on a print medium, and a rolling heating component for clamping the print medium with the pressure roller and heating the pressure roller. A fusing region is formed between the pressure roller and the rolling heating component. The toner fuser further includes a rolling preheating component installed on a side of the pressure roller for preheating the pressure roller and a part of the print medium not entering into the fusing region.
