Abstract
A seamed flexible belt with interlocking seam members having an outer layer including a polyvinylbutyral and an isocyanate, or a polyurethane from the reaction of polyvinylbutyral and an isocyanate, for use in the xerographic, contact electrostatic, digital and other like machines.
Claims21
An endless seamed flexible belt comprising a first end and a second end, each of said first end and said second end comprising a plurality of mutually mating elements which join in an interlocking relationship to form a seam, said seam comprising an adhesive, and said belt comprising a substrate and an outer layer comprising a polyurethane derived from a polyvinylbutyral and isocyanate.
An endless seamed flexible belt in accordance with claim 19, wherein said mutually mating elements comprise a first projection and a second receptacle geometrically oriented so that said second receptacle on the first end receives the first projection on the second end and wherein said first projection on said first end is received by said second receptacle on the second end to form a joint between the first and second ends.
An endless seamed flexible belt comprising a first end and a second end, each of said first end and said second end comprising a plurality of mutually mating elements which join in an interlocking relationship to form a seam, said belt comprising a polyimide substrate and an outer layer comprising a polyurethane derived from a polyvinylbutyral crosslinked with a block isocyanate.
An image forming apparatus for forming images on a recording medium comprising:
- a charge-retentive surface to receive an electrostatic latent image thereon;
- a development component to apply toner to said charge-retentive surface to develop said electrostatic latent image to form a developed image on said charge retentive surface;
- a transfer belt to transfer the developed image from said charge retentive surface to a copy substrate, wherein said transfer belt is an endless seamed flexible belt comprising a first end and a second end, each of said first end and said second end comprising a plurality of mutually mating elements which join in an interlocking relationship to form a seam, said transfer belt comprising a substrate and an outer layer comprising a polyurethane derived from polyvinylbutyral and isocyanate;
- and
- a fixing component to fuse said developed image to said copy substrate.
