Claims
- 1. An electrophotographic process for use with a photosensitive screen having a number of openings therein, said process comprising the steps of applying a voltage to the screen, applying an image light to said screen to form a primary electrostatic latent image thereon, applying ion flow through the screen from a corona source onto a chargeable member to form a secondary latent image thereon, repeating the ion flow application step to form subsequent secondary images by a single primary electrostatic latent image, and a preliminary step of applying a corona ion flow of the same polarity as the corona ion source and prior to said secondary latent image formation to stabilize the condition of the primary electrostatic latent image.
- 2. An electrophotographic process according to claim 1, wherein the stabilizing corona ion application is performed with a corona ion flow applied on the same side of the screen as the ion flow for the secondary latent image, and wherein an electrode is disposed at the other side of the screen.
- 3. An electrophotographic process according to claim 1, wherein the stabilizing corona ion flow is applied prior to repeating the ion flow application step to the primary electrostatic latent image.
- 4. An electrophotographic process for use with a photosensitive screen having a number of openings therein, said process comprising the steps of applying a voltage to the screen, applying an image light to said screen to form a primary electrostatic latent image thereof, applying ion flow through the screen from a corona source onto a chargeable member to form a secondary latent image thereon, repeating the ion flow application step to form subsequent secondary images by a single primary electrostatic latent image, wherein the first ion flow application step or a first few ion flow application steps are effected with a stronger ion flow than that of subsequent ion flow application steps to stabilize the condition of the primary electrostatic latent image.
