ABSTRACT:
A laser printer includes a photoconductor unit and a developer unit which are removable from a housing of the printer. A fixing device having a heating roller and a cover covering the heating roller is arranged in the housing adjacent to the photoconductor unit. The cover includes an upper wall and a plurality of ribs formed on the outer surface of the upper wall to prevent an operator's hand from directly touching the outer surface of the cover. That rib which is closest to the photoconductor unit is formed to prevent the operator's fingers from being caught by the fixing-device-side end portion of the photoconductor unit.
