Abstract

A resin composition comprises a polyphenylene sulfide resin and a nylon resin having a χ-parameter of less than 1.3 at 25° C., and has one glass transition temperature, and an image-forming apparatus comprises

• • a latent-image supporting member, and
  • an intermediate transfer member that supports a toner image transferred thereon from the latent-image supporting member, transfers the supported toner image onto an image receiving material,
  • the intermediate transfer member comprising a polyphenylene sulfide resin and a nylon resin having a χ-parameter of less than 1.3 at 25° C., and has one glass transition temperature.

Claims

1. An electrophotographic transfer belt, formed of a resin composition comprising a polyphenylene sulfide resin and a nylon resin having a χ

-parameter of less than 1.3 at 25°

C., and having one glass transition temperature, wherein the χ

-parameter is measured by executing a program SUSHI by using J-OCTA.

2. The electrophotographic transfer belt according to claim 1, wherein the glass transition temperature is 88°

C. or less.

3. The electrophotographic transfer belt according to claim 1, wherein the nylon resin has a χ

-parameter in a range from 0.01 to less than 1.3 at 25°

C.

4. The electrophotographic transfer belt according to claim 1, wherein the compounding ratio of the polyphenylene sulfide resin and the nylon resin is set to 60 to 99% by weight of the polyphenylene sulfide resin resin to 40 to 1% by weight of the nylon resin.
