Abstract
PURPOSE: To obtain visible images excelling in gradient by enhancing the reproducibility of picture image, by adjusting so that the intensity of electric field acting in the developing gap between the toner carrier and electrostatic image holder may vary in specific form.
CONSTITUTION: An electrostatic image holder 10 and a toner carrier 12 are opposedly provided in a developing section, keeping a certain gap, and AC voltage is applied to the toner carrier 12 from a power source 9, and a low frequency electric field is applied. In this constitution, in the space between the non-picture image part of the electrostatic image holder 10 and the toner carrier 12, the toner particles are caused to move reciprocally. In about 0.2sec after start of development, the AC voltage is attenuated to zero at the time constant of about 0.5sec, the toner particles are moved in one direction from the toner carrier 12 to the picture image part in the picture image part, and in one direction from the non-picture image part to the toner carrier 12 in the non-picture image part.
