Abstract
A cold pressure fusing apparatus for use in a xerographic copying machine for fixing a developed toner image to a copy sheet has the combination of elements including a first roller rotatably-mounted in the copying machine; a mechanism for driving the first roller; a second rotatably mounted roller in pressure contact with the first roller whereby a nip is formed through which copy sheets being fused pass; and a braking device operatively connected to the second roller for applying a controlled braking torque to the second roller, the torque being of such magnitude sufficient to facilitate the fusing of toner particles into the copy sheet without producing substantially any smudging of these particles, but of a magnitude insufficient to cause skidding of the second roller relative to the first roller.
