Abstract

Information is recorded on the surface of a recording member by signal-controlled non-impact printing means, such as a jet printer or meniscus printer. The recorded information is not necessarily visible, and comprises deposits formed by ion or electron or molecular donor material. The thus-recorded information is detected by pressure contacting the surface of the recording member with a dielectric surface to form a latent image thereon. The latent image may be read or detected as a voltage analog or it may be rendered visible by the attraction thereto of electroscopic marking particles. The deposit formed by such marking particles can be transferred onto a copy sheet or the like.
