ABSTRACT:
There is disclosed herein an image sensing device of an image pickup apparatus which produces an image signal corresponding to an optical image of an object taken through the image pickup apparatus. The image sensing device includes an photoconductive member responsive to the optical image on one surface thereof to produce an charge image corresponding to the optical image on the other surface under a predetermined electric field and a change holding member arranged so that an electrostatic latent image is formed on one surface thereof. The charge holding member is disposed to be opposed relation to the photoconductive member and first and second electrodes are respectively disposed on the photoconductive member and the charge holding member. Also included in the device is a voltage application circuit comprising a change-over switch and a power source so that a voltage of the power source is applicable to the first and second electrodes. The operation of the switch is controlled by a switch control unit so as to allow and interrupt the application of the voltage of the power source to the first and second electrodes. Discharging between the members is developed in response to application of the voltage thereto so that a charge image is formed on the charge holding member in correspondance with the charge image formed on the photoconductive member.
