Abstract
PURPOSE: To stabilize toner charge quantity and to prevent carrier deterioration, by charging toner by corona discharge, and by controlling a grid for controlling corona current to ensure an optimum recording density.
CONSTITUTION: Developer 13 attached to magnetic roller 2' for feeding charged toner is corona-charged with grid 11 for controlling corona current to develop static latent image 1. The developed image 4 is transferred onto recording paper 6 with corona charger 5 for transfer. The transferred image M illuminated with record density illuminating lamp, record density is detected by photodetector 8, the output detected is applied to voltage control circuit 9 for grid 11, compared to the desired density, circuit 9 is adjusted so as to form the desired density, and this output is applied to corona charger 10, thus permitting the charge quantity necessary for giving the optimum density to be provided to developer 3 by grid 11.
