Polyetherimide-b-polysiloxane block copolymers are useful as surface layers for fuser and fixing members in various printing devices, including electrostatographic imaging systems and ballistic aerosol marking devices. Optionally, the polyetherimide-b-polysiloxane block copolymers are fluorinated, or include at least 50% by weight siloxane.

摘要:
A process for making a multiple-layer elastomer-coated member, includes applying a coating of an elastomeric material to a supporting metallic substrate; and curing the elastomeric material by exposure to radiant energy in a radiant energy curing apparatus.
摘要:
Fuser members having improved thermal conductivity include an outer layer composed of elastomers and filler materials. The filler materials are oriented in the outer layer to provide directional thermal conductivity. Processes for forming the fuser members apply a liquid coating over a substrate and apply a magnetic field to the coating to orient the filler material. The coating is cured to retain the orientation of the filler material in the outer layer.
