Electrostatic image recording apparatus employing multi-apertured particle modulator is disclosed. The image recording apparatus receives digital electric image signals from an external device, such as a host computer, at a plurality of levels representative of the gradational values of the image to be formed. The image signals are distributed to a plurality of control electrodes which control the flow of toner particles to an image receiving member. The distributed digital image signals are converted to analog signals and a potential is applied to each control electrode based on the analog signal. The amount of toner particles passing through an aperture is controlled at a plurality of values by controlling the potential of a control electrode in a plurality of values based on image signals. As a result of the controls, a gradational dot can be formed. The resulting gradational image has high resolution.
