Texture Characterization of Chemically Prepared Toners
Abstract:Texture of toners affects many electrophotogaphic properties. The limited coalescence manufacturing method used to make chemically prepared toner (CPT) results in folded spheres with complex shapes. The thickness and quantity of these folds may be assessed by the amplification of light scattering. Evaluation of SEM photomicrographs shows a correlation of the fold thickness and light-scattering amplification. The angular scattering information indicates that the amplification occurs over all size scales rather than that of the fold thickness. Other texture information may be gathered from surface area and the cavity volume included in the folds. The included cavity volume of the folds may be assessed by the combination of spherical equivalent and aerodynamic diameters.

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.
