PROCESS AND DEVICE TO DEVELOP ELECTROSTATIC IMAGES Russian patent published in 1999 - IPC

FIELD: development of electrostatic images. SUBSTANCE: process of development of latent electrostatic image includes formation of fog from liquid, transfer of fog to development point along arc-shaped trajectory, transmission of fog between developing electrode and recording element where electric field is formed and removal of used fog from development point. Device to develop electrostatic images has aid to separate drops of fog with sizes of specified range and to remove drops with sizes outside the limits of specified range and aid to remove unused fog from development point. EFFECT: usage of developing agents based on water which develop with motion of drops. 47 cl, 5 dwg
