Crystal structure of an azo Fe-complex used as a charge control agent and its electrical properties
Abstract:The title compound (azo Fe-complex) is a well-known chargecontrol agent (CCA) used widely in electrophotography. Structure analysis as well as electrical measurements has been carried out in the present study in order to support our charge control mechanism that is based upon local heating and charge transfer through conductive channels at the “toner/carrier” contact. Methanol or acetone-solvated single crystals were isolated from solution in methanol or acetone, respectively. The former is found to crystallize in space group of P-1 while P21/n in the latter crystal. The electrical conductivity of these crystals increases exponentially with temperature and the value around 100 °C is two-three orders of magnitude higher than that of room temperature.

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.
