20080199228 | COLOR IMAGE FORMING APPARATUS AND PROCESS CARTRIDGE ATTACHED THERETO - In a color image forming apparatus comprising a plurality of developing devices each provided with a developing roller structured with a developing sleeve and a fixed magnetic pole member, an agitating member, a recovering and feeding member, a regulating member and a developing device casing member, at least one of the plurality of developing devices has a different developer storing capacity and a different outer diameter of the recovering and feeding member for the other developing devices and has the same angle allocation values among the plurality of fixed magnetic poles in the fixed magnetic pole member. | 08-21-2008 |
20100231972 | Image Forming System - An image forming system, having means for storing usage histories of latent image carriers, developer, or the like and maintenance cycles of image forming apparatuses and having a function for selecting image forming apparatuses outputting an image based on the usage history data or the maintenance cycles, in order to achieve uniform output image qualities. By managing the usage histories so as to achieve approximately the same deteriorated conditions of the latent image carriers of the image forming apparatuses, the image forming apparatuses can be put in the same condition and thus the output image qualities can be approximately the same in the image forming apparatuses. Additionally, the maintenance cycles can be adjusted to be approximately the same in the image forming apparatuses. Otherwise, maintenance periods can be controlled so as not to overlap in the image forming apparatuses. | 09-16-2010 |
20110052222 | IMAGE FORMING APPARATUS - An image forming apparatus having a development apparatus that includes: a developer storing part; a developer supply mechanism; and a surplus developer removing section; wherein the developer supply mechanism includes: a toner storing part; a carrier storing part; a developer conveying path and a conveying mechanism, both are arranged between the toner storing part and the developer storing part, and between the carrier storing part and the developer storing part; wherein the developer conveying path includes a toner ejection outlet through which a toner stored in the toner storing part is ejected and a carrier ejection outlet through which a carrier stored in the carrier storing part is ejected, and a supplying developer ejection outlet through which a supplying developer is ejected to the developer storing part; and wherein the conveying mechanism is adapted to convey the toner and the carrier while stirring them. | 03-03-2011 |
