Claims
- 1. A toner system for applying toner to the surface of a recording medium containing a latent electrostatic image comprising:
- a toner applicator having a toning channel in fluid communication with said recording medium for applying toner to said recording medium, said toner applicator also having an air channel peripherally surrounding said toning channel,
- air supply means for directing air into said air channel surrounding said toning channel such that said toner is confined within said toning channel,
- a support backing for holding said recording medium in fluid communication with said toning channel, said support backing comprised of a planar member disposed above said recording medium such that said recording medium is disposed between said planar member and said toner applicator.
- 2. A toner system for applying toner to the surface of a recording medium comprising:
- means for electrostatically charging a recording medium having opposed first and second surfaces,
- toner applicator means having a toning channel in fluid communication with said recording medium for applying toner to a first surface of said recording medium, said applicator means also having an air channel peripherally surrounding said toning channel,
- air supply means for directing air into said air channel surrounding said toning channel such that said toner is confined with said toning channel,
- support means for holding said recording medium in communication with said applicator means, said support means comprised of a planar member disposed above and facing the second surface of said recording medium such that said recording medium is disposed between said planar member and said toner applicator means.
- 3. A method for applying toner to the surface of a recording medium carrying a latent electrostatic image comprising the steps of:
- peripherally surrounding a toner applicator channel with an air channel,
- supporting said recording medium in fluid communication with said toner applicator channel using a planar support backing member placed above and facing said recording medium such that said recording medium is disposed between said planar member and said toner applicator,
- bringing said recording medium into fluid contact with said toner applicator channel,
- supplying liquid toner to said toner application channel, and
- directing air into said air channel such that said toner is confined within said toner applicator channel.
