Abstract

Fuser apparatus and support structure therefor characterized by the provision of pairs of support brackets which independently support a heated fuser roll structure and a resilient backup roll structure to form a nip therebetween through which copy sheets carrying toner images pass for fusing of the toner images to the copy sheets. The brackets supporting the backup roll are rigidly affixed to the planar portion of a channel-shaped member while the brackets supporting the fuser roll structure are pivotably attached to the backup roll brackets by means of flexure hinges. A pair of adjustable fasteners utilized for applying contact pressure between the two roll structures couples the fuser roll brackets to the backup roll brackets at the sides thereof opposite to the flexure hinges.
