Photoreceptor is a central device in digital printers. The outer layer, Charge Transport Layer made up of polycarbonate and Charge Transport Molecule is prone to abrasion by stresses of developing system or cleaning system when it is repeatedly used in printing process. The abrasion of the photoreceptor causes deterioration of electrical properties such as lowering sensitivity or lower charging and results in irregular image such as lower image density and image stain. Single and multiple coating were made with filled and unfilled binder polymers and their modulus and hardness were measured by nano-indenter. Charge Transport Molecule reduced modulus and hardness thus increasing photoreceptor wear rate. Nano-filler silica in the polymer either polycarbonate or polyester increased modulus and hardness with higher photoreceptor life.

More about this publication?
  • For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
