Charge Control of the Polyester Color Toners on Non-magnetic Single Component Development
Abstract:Non-magnetic single component development system have widely been used in desk top color laser printers, however, the charge control of the toner is very difficult compared with that of the dual component developer because of no carrier. We have investigated the charge control of single component color toners. Charging behavior at mixing with a carrier and flowability of the toner are closely related to the image quality (background, image density). Especially, resistance of the toner, quick charge and saturated charge ability influence to the image quality.
In this paper the most suitable design of the charge control agent and the surface additive for single component color toners is also reported. The application of the charge control agent and the surface additive is very important for the charge stability on single component development. For instance, it is possible to decrease the background by decreasing the amounts of the surface additive.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
