Patent number: 6177947Abstract: Apparatus for forming an image, comprising a storage for storing a digitized image and a receiver. The receiver includes a matrix, a thermomeltable material disposed in the matrix having a transition temperature range which is above room temperature wherein the viscosity of the thermomeltable material decreases substantially from below to above the transition temperature range, and field-driven particles immersed in the thermomeltable material, so that the particles change optical densities in response to an applied electric field when the thermomeltable material is above the transition temperature range and is stable at temperatures below the transition temperature range. An array of electrodes selectively applies electric fields at an image forming position on the receiver. The apparatus heats the receiver to control the temperature of the receiver to control the response of the field-driven particles in the receiver.Type: GrantFiled: April 2, 1998Date of Patent: January 23, 2001Assignee: Eastman Kodak CompanyInventors: Xin Wen, Steven D.
