Abstract

Abstract A printing machine in which a recording medium has a latent image recorded thereon. A housing stores a supply of liquid developer material therein. The housing is operatively associated with a donor member for substantially uniformly coating liquid developer material thereon. The donor member is spaced from the recording medium. As the donor member moves, it transports the developer material to a development zone wherein the latent image recorded on the recording medium attracts at least the toner thereto to form a developed image thereon. A multicolor image may be formed by repeating this process for different developer materials.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 144 words
A printing machine, including: a recording medium adapted to have a latent image recorded thereon; a housing storing a supply of liquid developer material comprising a liquid carrier having toner particles dispersed therein, said housing storing a plurality of different color liquid developer materials; and a donor member, spaced from said recording medium to define a gap there between, operatively associated with said housing so as to be coated with the liquid developer material, said donor member being movable to transport the developer material to a region opposed and spaced from said recording medium so that the latent image recorded thereon attracts the toner particles across the gap to form a developed image on said recording medium, said housing, coating said donor member with different color liquid developer materials so as to develop different latent images recorded on said recording medium in different colors.
Claim 2
Dependent Claim 144 words
A printing machine, including: a recording medium adapted to have a latent image recorded thereon; a housing storing a supply of liquid developer material comprising a liquid carrier having toner particles dispersed therein, said housing storing a plurality of different color liquid developer materials; and a donor member, spaced from said recording medium to define a gap there between, operatively associated with said housing so as to be coated with the liquid developer material, said donor member being movable to transport the developer material to a region opposed and spaced from said recording medium so that the latent image recorded thereon attracts the toner particles across the gap to form a developed image on said recording medium, said housing, coating said donor member with different color liquid developer materials so as to develop different latent images recorded on said recording medium in different colors.
Claim 3
Dependent Claim 14 words
A printing machine according to claim 1, wherein said recording medium includes a sheet.
Claim 4
Dependent Claim 22 words
A printing machine according to claim 2, further including an electrostatic recording head adapted to record the latent image on said sheet.
Claim 5
Dependent Claim 15 words
A printing machine according to claim 3, wherein said donor member includes a donor belt.
Claim 6
Dependent Claim 15 words
A printing machine according to claim 3, wherein said donor member includes a donor roll.
Claim 7
Dependent Claim 34 words
A printing machine according to claim 1, wherein said donor member deposits different color toner particles on the different latent images in superimposed registration with one another to form a composite multicolor developed image.
