Abstract
An electrophotographic endless belt has a beltlike substrate and a meandering-preventive member attached to the inner peripheral surface of the beltlike substrate via a pressure-sensitive adhesive, double-coated tape. The pressure-sensitive adhesive, double-coated tape is a pressure-sensitive adhesive, double-coated tape having i) a reinforcing base material and ii) pressure-sensitive adhesive layers on both sides of the reinforcing base material. The reinforcing base material has a thickness of from 25 μm or more to 200 μm or less, and the pressure-sensitive adhesive layers on both sides each have a thickness of 200 μm or less and at least one of the pressure-sensitive adhesive layers has a thickness of from more than 100 μm to 200 μm or less, and the meandering-preventive member has a hardness of from 15° or more to 70° or less. Also disclosed are a process cartridge and an electrophotographic apparatus which have the electrophotographic endless belt as an intermediate transfer belt.
