Fixing device for image forming apparatus.

摘要

A fixing device has a hollow fixing roller, and a pressing roller pressingly contacting the fixing roller to cooperate with the fixing roller to form a nip portion therebetween so as to fuse and fix a toner image onto a recording paper. The fixing device also has a heating element arranged within the fixing roller at a position eccentric from the axis of the fixing roller toward the nip portion, to locally heat the inner wall of the fixing roller at a position corresponding to the nip portion, so as to decrease the time necessary to heat the fixing roller, to prevent offset, and to prevent the recording paper from being wound onto the fixing roller. <IMAGE>
