ABSTRACT:
An image forming apparatus including electric field control member for directly controlling the flow of charged particles with an electric field, supply device for supplying the charged particles to the electric field control member, and a counter electrode disposed so as to face the supply device through the electric field control member. The electric field control member includes control electrodes for controlling the electric field and a base member disposed at the counter electrode side of the control electrodes. The control electrode and the base member have apertures and each aperture of the base member, at least at a side away from the apertures in the control electrode, is larger in diameter than the aperture of the control electrodes. The control electrode is pressed against the supply device such that the control electrode is equally bent to either side of a plane passing through the apertures in the control electrode.
