DIRECT ELECTROSTATIC PRINTING METHOD AND APPARATUS

摘要

A direct electrostatic printing device and method for printing an image with improved printing speed without degradation in printing quality. A length of time of print sequences are restricted to be at least substantially equal a length of time a substantial part of a toner jet is travelling in a volume which comprise influential forces such as deflection forces above a predetermined value, to enable dot degradation due to increased printing speed to be eliminated or at least reduced. Refinements to enable the reduction of the volume are also disclosed. Preferably a length of time of the print sequences are also shorter than a length of time a toner jet is travelling from a pigment particle delivery to an image receiving medium to ensure high printing speeds.
