    Abstract: Method and apparatus for transferring a developed image from an image bearing member to a receiver substrate in a Contact Electrostatic Printing (CEP) system may be provided according to the present invention. The developed image is formed of a development material having a mixture of carrier fluid and pigmented polymeric particles, the composition of such mixture being selected for its characteristic behavior at an elevated temperature for transitioning to a substantially single phase. The method includes the steps of developing an image onto an image bearer using the aforementioned development material; concentrating the developed image; heating the developed image to a temperature at which the polymeric particles and the carrier fluid achieve a substantially single phase condition, so as to form a transferable image; and transferring the transferable image to a receiver substrate such as a paper sheet.
