Process cartridge and image forming apparatus having particular arrangement of electrical contacts

Process cartridge comprising grounding, charging bias, and developing bias contacts and input and output contacts, and electrophotographic image forming apparatus to which the process cartridge is detachably mountable

PURPOSE:To obtain a separation membrane module which is stable against external contact of an org. solvent and consists of a transparent case by coating the outer surface of the module case with a resin material having higher chemical resistance than the case material. CONSTITUTION:The separation membrane module consists of a polysulfon hollow fiber ultrafiltration membrane fixed to a transparent polysulfon cylindrical case with an epoxy resin. The outer exposed surface of this module case is coated with an epoxy resin coating layer having higher chemical resistance and transparency. Thus, the separation membrane module having high heat resistance and org. solvent resistance is obtained.
