ABSTRACT:
The present invention relates to a method for improving the print quality of an image recording apparatus in which charged particles are transported from a particle source and deposited in an image configuration on an information carrier. Variable control voltages are supplied to control electrodes to permit or restrict the transport of charged particles from the particle source during a predetermined print time. The control voltage levels, the print time length or the voltage levels and the print time length are dimensioned in relation to the specific distance between each control electrode and the particle source. The present invention relates also to a device for accomplishing the method.
