Electrophotographic developing system comprising toner having specific particle size distribution |
摘要 |
A developing system for an electrostatic image reproduction machine comprising a mono-component developer having toner particles of selected diameters dispersed therein; container for holding the developer; a developer sleeve for receiving a quantity of the developer from the container; a restriction member for forming a thin layer of the developer on the sleeve; a device for impacting an electric charge to the developer layer; and a latent image retainer for selectively receiving the electrically charged layer for forming a visible image. The developer satisfies the expression d75/d25</=d50/40+1.2 where d25, d50 and d75 represent diameters of toner particles when the percentage by volume or by weight of toner particles of that diameter as compared to the total volume or weight of the developer is 25%, 50% and 75%, respectively. A developer and method for making the developer are also described.
