Electrostatic latent image forming medium, image forming apparatus including the electrostatic latent image forming medium and method of forming an electrostatic latent image

An electrostatic latent image forming medium, comprising:

• 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 method of forming an image, comprising:

• charging an image forming apparatus imaging surface with a potential via a charge roller;
• selectively controlling the potential of selected pixel electrodes of a plurality of pixel electrodes, the plurality of pixel electrodes under an imaging surface on which an electrostatic latent image is to be formed such that the potential of the selected pixel electrodes is different than the potential of the imaging surface, the selectively controlling being in accordance with the electrostatic latent image to be formed;
• and
• transferring the electrostatic image to a printing medium.
