Patent JP-H07168450-A (JP)
Title: Developing method
Inventor: WAKAISA MITSUSHI
IPC: G03G15/09
Filed: 1993-12-14
Abstract: PURPOSE:To obtain a method by which developing can be performed without impressing bias voltage by forming an electret layer having the permanent charge of the same polarity as the electrostatic charging polarity of developer on the surface of a non-magnetic sleeve positioned in a developing area. CONSTITUTION:The electret layer 8 having the permanent charge of the same polarity as the electrostatic charging polarity of magnetic toner 20 is formed on the surface of a non-magnetic sleeve 2 positioned in the developing area A. Since electric repulsive force acts on the magnetic toner 20 forming a magnetic brush 7 from the electret layer 8, in the area A the magnetic toner 20 is easily shifted to the surface of a photoreceptor without impressing the bias voltage, and adheres to a latent image forming part so as to develop the image. Therefore, a bias power source is not necessitated, so that the developing device is made compact, the cost of the device is made low and the device is useful for resource economization. Since attractive force acts from the electret layer 8 on the toner eletrostatically charged to have a reverse polarity, the scattering of the reversely electrostatically charged toner is effectively prevented and the image having no fogging is formed.
