Abstract
The present invention relates to methods and devices for creating high shear forces to disperse high solids toner into a working developer solution. The high solids toner have a toner particle concentration of at least 40% by weight of the working developer solution. An image forming device having such dispersion system includes a latent image device for creating a latent image; a developer device for developing the latent image; a transfer device for receiving the developed latent image onto a predetermined image medium; a developer supplying device for recirculation of a working developer solution through the developer device; a replenishing device for supplying concentrated developer solution preferably at a rate equivalent to a consumption rate of the working developer solution in the developer device; and a dispersion device for dispersing the concentrated developer solution from the replenisher device into the working developer solution of the developer supplying device. The dispersion device includes a rotatable member, a mechanism for rotating the rotatable member, and a stationary member for creating a high shear force at a contact area between the rotatable and stationary…
