Abstract
The present invention is a method and apparatus for printing using an intermediate member acting as a receptor for marking particles representing an image. The marking particles may be deposited directly or indirectly on the member, after which time the member is exposed, via an internal heat source, to an elevated temperature sufficient to cause the melting and coalescing of the marking particles. Subsequently, the intermediate member is advanced so as to place the tackified marking particles present on the outer surface thereof into intimate contact with the surface of a recording sheet.
Claims11
A recording apparatus for producing a color image on a recording sheet, comprising:
- an intermediate member;
- first marking means for depositing marking material of a first color on said intermediate member to produce a marking image thereon;
- a heater, in communication with said intermediate member, for heating said intermediate member so as to form a tackified marking image thereon;
- second marking means for depositing marking material of a second color on the tackified marking image forming a composite tackified marking image on said intermediate member;
- means for transferring the composite tackified marked image to the recording sheet;
- and
- first ion generating means for recording an electrostatic latent image on said intermediate member, said first marking means developing the electrostatic latent image with the marking material of the first color to produce a developed image on said intermediate member.
A method for producing a color image on a recording sheet, comprising:
- depositing marking material of a first color on a intermediate member;
- heating the marking material deposited on the intermediate member to form a tackified marking image and wherein said heating step comprises maintaining the intermediated member ranging from about 130.degree. C. to about 150.degree. C., and further comprises using an intermediate member having a substrate layer and an insulating top layer coupled therewith and wherein said using step comprises using substrate layer has a thickness ranging from about 0.1 mm to about 1.0 mm and a resistivity ranging from about 10.sup.6 ohm-cm to about 10.sup.11 ohm-cm;
- and
- depositing marking material of a second color at least partially on the marking particles of the first color forming a composite tackified marking image.
A method for producing a color image on a recording sheet, comprising:
- depositing marking material of a first color on a intermediate member;
- heating the marking material deposited on the intermediate member to form a tackified marking image and wherein said heating step comprises maintaining the intermediated member ranging from about 130.degree. C. to about 150.degree. C., said heating step comprises using an intermediate member having a substrate layer and an insulating top layer coupled therewith and wherein said using step comprises using insulating top layer has a thickness ranging from about 10 microns to about 100 microns, a dielectric constant ranging from about 10 to about 1.0, and a resistivity between 10.sup.12 ohm-cm to about 10.sup.14 ohm-cm;
- and
- depositing marking material of a second color at least partially on the marking particles of the first color forming a composite tackified marking image.
A method for producing a color image on a recording sheet, comprising:
- recording an ionographic latent image on an intermediate member;
- developing the ionographic latent image with marking material of a first color on the intermediate member;
- heating the marking particles deposited on the intermediate member to form a tackified marking image;
- and
- depositing marking material of a second color at least partially on the marking particles of the first color forming a composite tackified marking image;
- and
- transferring the composite tackified marked image to the recording sheet.
