    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： Positive liquid electrographic toner compositions are provided comprising a liquid carrier having a Kauri-Butanol number less than about 30 mL and a plurality of positively charged toner particles dispersed in the liquid carrier. The toner particles comprise a polymeric binder comprising at least one amphipathic graft copolymer comprising one or more S material portions and one or more D material portions. The toner composition additionally comprises a charge control adjuvant that is an acid or a base. These compositions have surprising bulk conductivity and charge per mass properties, particularly as the toner particles are depleted from the toner composition during printing operations.

    摘要： The invention provides liquid toner compositions in which the polymeric binder is chemically grown in the form of copolymeric binder particles dispersed in a liquid carrier. The polymeric binder includes one amphipathic copolymer that comprises the residue of a Soluble High Tg Monomer. The toners described herein exhibit surprisingly low fusion temperatures, yet are surprisingly resistant to blocking, are non-tacky and are resistant to marring and undesired erasure.
