Abstract
An electrophotographic printing machine in which an electrostatic latent image recorded on a photoconductive member is developed with a liquid developer material having at least a liquid carrier with pigmented particles dispersed therein. The developed image is transferred from a photoconductive member to a sheet of support, material. Heat and pressure are applied to the developed image on the sheet of support material to vaporize substantially all of the liquid carrier transferred to the sheet of support material and to substantially permanently fuse pigmented particles to the sheet of support material in image configuration.
Claims14
A reproducing machine of the type having a latent image recorded on a member, wherein the improvement includes:
- means for developing the latent image recorded on the member with a liquid developer material comprising at least a liquid carrier having pigmented particles dispersed therein;
- means for transferring the developed image from the member to a sheet of support material;
- a pressure roll;
- and
- a heated fusing roll cooperating with said pressure roll to form a fusing nip and for advancing the sheet of support material having the developed image thereon therethrough, said fusing roll cooperating with said pressure roll to advance the sheet of support material and to apply heat and pressure to the developed image on the sheet of support material so as to vaporize substantially all of the liquid carrier transferred to the sheet of support material and to substantially permanently fuse the pigmented particles to the sheet of support material in image configuration as the sheet of support material advances through the fusing nip with increased image density and uniformity at a lower energy input.
