Abstract
Official abstract text for this publication.
The present invention provides a charging member which has a low compression set and which can suppress the generation of image defects. A layer of an unvulcanized rubber composition including an unvulcanized acrylonitrile butadiene rubber and N,N′-methylenebis(1,4-phenylene)dimaleimide is vulcanized.
First claim
Opening claim text (preview).
The invention claimed is: 1. A charging member comprising a conductive elastic layer, wherein said elastic layer is formed by vulcanizing a layer of an unvulcanized rubber composition including an unvulcanized acrylonitrile butadiene rubber, and N,N′-methylenebis(1,4-phenylene)dimaleimide. 2. The charging member according to claim 1 , wherein: said elastic layer is formed by further irradiating a surface of the layer of the rubber composition with ele…
