METHOD FOR OPERATING ELECTROPHOTOGRAPHIC COPYING APPARATUS

摘要

There is disclosed a method for operating an electrophotographic copying apparatus having a latent image forming unit for forming an electrostatic latent image on a recording medium, a development unit for visualizing the electrostatic latent image with a developer containing toner and carrier to produce a visible toner image, and a fixing unit for fixing the toner image. In this operation method, the development unit is raced until the amount of charge on the toner in the developer reaches a predetermined level, and thereafter a usual electrophotographic copying procedure commences, whereby reduction in density of developed images during the initial operation of the electrophotographic copying apparatus can be prevented and developed images of high quality can be obtained.
