Patent ID: 7388594

Claim:
An image forming apparatus, comprising: an electrostatic latent image forming medium including a frame, an imaging surface on which an electrostatic latent image is to be formed, the imaging surface being supported by the frame, and an alteration mechanism for altering the electrostatic latent image on the imaging surface, the alteration mechanism being between the frame and the imaging surface and including a thin film transistor array on a surface of the frame, the thin film transistor array including a plurality of thin film transistors; and a capacitor layer formed on the thin film transistor array, the capacitor layer including a common electrode and a dielectric layer stacked on the common electrode; a signal supply for supplying a signal to the alteration mechanism in accordance with the electrostatic latent image to be formed; and a transfer unit for transferring the electrostatic latent image to a printing medium.
