METHOD FOR COMPREHENSIVELY IMPROVING FUNCTIONS OF AN ELECTROGRAPHIC IMAGING DEVICE

摘要

A method for improving functions of an imaging apparatus comprises: replacing a mechanically damaged or aged part whose function is unrecoverable in an imaging apparatus with a new part with the same function and the same structure; substituting a charging roller (22) for a corona wire (22a); substituting a fixing film (41) having an electronic ceramic heating structure (411) for a fixing roller (41a) having a heating tube structure; and reducing the fixing temperature by adopting a low temperature fixing toner, and setting the fixing temperature to a range of 100°C to 140°C.
