摘要： A developer, process cartridge and electrophotographic apparatus that includes the process cartridge and developer, which has as component parts, a main toner body, and an additive that enhances the fluidity of the main toner body. A mixing ratio of the additive to the main toner body, ensures that a contact charger, will not become contaminated, with excess additive that bypasses a cleaning device. While the additive ensures a proper fluidity of the main body of the toner, an excessive amount of additive, beyond a predetermined range, is avoided, so as to prevent the additive from contaminating the contact charger, thus enhancing the lifespan of the contact charger while maintaining image quality.

摘要： In an image forming apparatus, a developing device has a first developer carrier for depositing a developer thereon, a regulating member for regulating the amount of the developer deposited on the first developer carrier, and a second developer carrier having an elastic surface, and contacting the first developer carrier while biting into it by a predetermined amount. The developer is provided with a preselected degree of fluidity. Hence, even when the same portion of the surface of the second developer carrier runs a plurality of times past a position where the two developer carriers contact each other without any developer being fed from the second developer carrier to an image carrier, the first developer carrier can surely strip the developer from the second developer carrier. As a result, a developer on which a predetermined amount of charge is deposited is transferred from the first developer carrier to the second developer carrier. This successfully protects images from defects. Particularly, when the developer has a zinc stearate content of greater than 0.1 wt %, it is possible to prevent the developer from melting and adhering to a member which regulates the developer.

摘要： The improved image forming method reduces the chance of toner particles of adhering or filming on the surfaces of impression members, thereby enabling the formation of high-resolution image in a consistent and reliable manner. The method uses a charging member 4 for contact charging a latent image carrier 1, a developing member 11 for impression development of a pattern of latent electrostatic image, a transfer member 18 for impression transfer of the developed toner 10, and an impression cleaning member 23 for cleaning the latent image carrier 1 after toner transfer. The toner to be used satisfies one of the following conditions: that it should have an external additive added in an amount of 0.4 to 1.2 wt %; that it should have a volume resistivity of at least 10.sup.17 .OMEGA.cm; that it should incorporate a release agent in an amount no more than 5 wt %; or that it should not include large amounts of fine particles with a size of 5 .mu.m and less, or coarse particles with a size of 12.7 .mu.m and more.
