Improved methods and apparatus for transfer method for generating an image to a receiving medium such as plain paper

摘要

(57) method and apparatus for producing an image on plain paper from the image data using [Abstract] photoreceptors. Imagewise distribution of charge is generated on the photoreceptor corresponding to the image data. It is applied to the photoreceptor, this liquid ink having a solid charged colored particles have an effective glass transition temperature of 25 ℃ below, to form an image by forming an imagewise distribution of the colored particles to the photoreceptor on . This liquid ink has in the image solids of more than 75 percent by volume. Film forming means (82, 84), a film of the liquid ink image to 0.5 seconds is disposed in contact with the photoreceptor immediately after application means (52,60,68,76) I dried to form. This image is dried in photoreceptors on. Then the image is transferred to the (38) elastic transfer roller for forming a transfer nip of the first pressurized by the photoreceptor. The elastic transfer roller is heated up to 100 ℃ from 50 ℃. Then the image is transferred to plain paper through the nip under pressure which is formed between the backup roller and the transfer roller (40) to (36). Surface energy of the release layer of the optical receiver is smaller than that of the elastic transfer roller. The surface energy of the elastic transfer roller is smaller than that of the liquid ink. Surface energy of the liquid ink is smaller than that of plain paper.
