    摘要: Method and apparatus for producing an image on plain paper from image data using a photoreceptor. An image-wise distribution of charges is produced on the photoreceptor corresponding to the image data. A liquid ink having solid charged pigmented particles, the liquid ink having an effective glass transition temperature of less than 25 degrees Celsius is applied to the photoreceptor forming an image-wise distribution of the pigmented particles on the photoreceptor to form the image. The liquid ink has greater than seventy-five percent by volume fraction of solids in the image. A film forming means is positioned against the photoreceptor immediately following the application means to dry the image of the liquid ink to film forming within 0.5 seconds. The image is dried on the photoreceptor. The image is then transferred to an elastomeric transfer roller which forms a first transfer nip under pressure with the photoreceptor. The elastomeric transfer roller is heated to from 50 degrees Celsius to 100 degrees Celsius. Subsequently, the image is transferred to plain paper through a nip formed between a backup roller under pressure with the transfer roller. The release layer of the photoreceptor has a surface energy which is less than a surface energy of the elastomeric transfer roller which in turn is less than a surface energy of the liquid ink which in turn is less than a surface energy of the plain paper.

    摘要: An electrographic imaging process is described in which electrostatic images are toned in sequence to form a multicolor intermediate image on a temporary dielectric receptor. The intermediate image is then transferred to a permanent receptor. Certain relative properties of the toner and the intermediate image, such as surface energy, T.sub.g, work of adhesion, and complex dynamic viscosity, have been found to be important to the production of good final images.
