Abstract
An electrophotographic endless belt which contains a polyamide resin and an additive A comprising at least one selected from the group consisting of copper(I) iodide, potassium iodide, copper(I) chloride and potassium chloride, and has a volume resistivity of from 1×106 to 1×1014 Ωcm. Also disclosed are a process for producing the electrophotographic endless belt and an electrophotographic apparatus having the electrophotographic endless belt.
Claims9
An electrophotographic endless belt comprising a polyamide resin and an additive A,
- wherein said additive A is at least one selected from the group consisting of copper(I) iodide, potassium iodide, copper(I) chloride and potassium chloride, and
- said electrophotographic endless belt has a volume resistivity of from 1×106 to 1×1014 Ωcm.
A process for producing an electrophotographic endless belt which comprises a polyamide resin, carbon black and an additive A comprising at least one selected from the group consisting of copper(I) iodide, potassium iodide, copper(I) chloride and potassium chloride, and has a volume resistivity of from 1×106 to 1×1014 Ωcm;
- said process comprising the step of mixing said polyamide resin, said carbon black and said additive A before said polyamide resin and said carbon black are compounded.
