摘要： An intermediate transfer member suitable for full-color image formation by electrophotography is formed by an elastic base layer and a fibrous core member embedded with the base layer. The core member is formed of fibers which are disposed within the base layer at a spacing between adjacent fibers of 50-3000 &mgr;m. As a result, the intermediate transfer member is reinforced to exhibit improved superposed transfer performance free from color deviation while retaining good transfer performance.
