Abstract

PURPOSE:To prevent fog on the ground of an image and to obtain stable image density, by triboelectrifying toner to the range of 5-25muc/gr. CONSTITUTION:Nonmagnetic toner 7 in a toner container 3 is conveyed through a toner feeding roller 4, a charging roller 5 to a fur brush roller 6, where brushes 4a, 5a, 11 rub one another to triboelectrify the toner 7. This is drawn with a cyclone 12, and its charged quantity is measured with a Q meter 17, and its quantity is regulated in the range of 5-25muc by controlling rotation speed of the roller 5, and contact width of the brushes 4a, 5a, 11 or toner concentration, thus permitting fog on the ground of an image due to noncharged toner to be prevented and stable image density to be obtained.
