Title: Electrostatic latent image forming method
Inventor: YAMAMOTO HAJIME
IPC: G03G13/04
Filed: 1983-07-11
Abstract: PURPOSE:To improve a color resolving power, and also to prevent a fog by exposing the same image by changing an incident angle from aparticle adhering surface of a photosensitive body, to a light transmitting particle adhering electrostatically to the surface of an electrophotographic photosensitive body containing a photoconductive substance. CONSTITUTION:The same image is exposed by changing an incident angle from a particle adhering surface of a photosensitive body, to a light transmitting particle adhering electrostatically to the suface of an electrophotographic photosensitive body containing a photoconductive substance. As for the photosensitive body 2, that which has vapor-deposited or applied Se, ZnO, etc. onto a conductive base board is used. When using a ZnO photosensitive body, it is charged electrostatically to negative, a light transmitting particle is sprinkled to it and when an image exposure is executed from the direction A of diagonal left 20 deg., a condensed image under the particle is shifted to the right direction. When this incident light is moved to the right and shifted to an incident angle B, a latent image under the particle becomes as shown by 5. In this way, by varying an incident angle at the time of exposure, an image condensing area of the lower of the particle can be expanded. In this case, a latent image under a light non-transmitting particle becomes as shown by 6. In this way, a difference of an electrostatic attraction of the light transmitting particle and the light non-trnsmitting particle can be made large even by a little exposure quantity, and a color resolving power of an image can be impressed.
