BELT FOR ELECTROPHOTOGRAPHY, ELECTROPHOTOGRAPHIC PHOTORECEPTOR-INTERMEDIATE TRANSFER BELT INTEGRATED TYPE CARTRIDGE AND IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a belt for electrophotography free from image variations and having high durability, and an electrophotographic photoreceptor-intermediate transfer belt integrated type cartridge and an image forming apparatus.

SOLUTION: The belt for electrophotography is constituted of thermoplastic resin mixture, whose viscosity at the outflow start temperature +5°C of a flow tester is 1.2 or more times and less than 50 times as high as the viscosity at the outflow start temperature +15°C of the flow tester. The belt for electrophotography has surface waviness whose wavelength is ≥0.1 mm and <20 mm on average in the peripheral direction of the belt, and the average wave height of the surface waviness is ≤30 μm. The electrophotographic photoreceptor-intermediate transfer belt integrated type cartridge and the image forming apparatus are formed by using the belt.
