Title: Developer and method of copying thereby
Inventor: TANAKA SUSUMU
IPC: G03G15/16
Filed: 1978-03-09
Abstract: PURPOSE: To improve the resolution of electrophotographic image, by using a developer consisting of a high-resistivity magnetic toner and an insulating non- magnetic toner.  
     CONSTITUTION: A photosensitive material 1 is charged by a charger 2 and light is irradiated to the material by an image exposure unit 3, thereby forming an electrostatic lantent image. A bias voltage of the same polarity as the latent image is applied to an electroconductive sleeve 10 of a developing unit 4. The developer consists of 85 to 98% by weight of the high-resistivity magnetic toner of 10 10  to 10 14 Ω.cm in volume resistivity and 2 to 15 % by weight of the insulating non- magnetic toner. The electrostatic latent image is developed by a magnetic brush so that the magnetic toner and the non-magnetic toner adhere to the image part of the photosensitive material 1 and the non-magnetic toner adheres to the non-image part of the material 1. The toners adhering to the image part are transferred onto a copy paper 8 by a charger 5 and then fixed by a fixing unit 9. The toner remaining on the photosensitive material 1 is scraped off by the blade 20 of a cleaner 6 and  hen returned to the developing unit 4 through a pipe 22.

The shell 3 has a dual structure of, for example, a copper cylindirical conductive layer 11 and an iron cylindrical magnetic layer 12. When multiphase alternate currents which are out of phase are applied to the adjacent coils 7, a moving magnetic field is generated in each coil 7 and thrust is then generated. Due to the thrust, the bar moves in the shell 3 and a curtain 5 connected to the bar 4 is driven.
