Charged Particle Adhesion Internal to and External to an Electrostatic Field
Abstract:Toner adhesion to a polyimide film substrate has been measured both inside and outside of an electrostatic field. Toner removal outside of an electrostatic field was done with a blow-off tool described previously. In-field measurements were done with a parallel plate device where the top plate was held at a known voltage and the lower plate grounded. Toner samples were astransferred to a polyimide intermediate transfer belt. Charged parallel plates have a propensity to experience low-field breakdown, as charges are highly mobile on the plate surface. To address that issue a thin insulation layer between the two plates was used. In-field and out-of-field toner removal responds differently to toner charge. A hypothesis of image dipole cancellation with electric field is proposed.

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.
