Means for developing electrophotographic images

Charger for electrographic surfaces

A method of producing a liquid developer for electrostatic images by subjecting a low density polymer to a solvent of relatively smaller molecular size so that the solvent activates the polymer chains to form a modifying carrier liquid, and then applying the modifying carrier liquid to particles of solid toner material so that by dilatant action the molecular bonds of the particles are broken to produce a fine developer held in a lattice structure.

Liquid developers for electrostatic images

A method of transferring images from one surface to another, which, instead of using a steady field uses a corona to build up a charge on a roller which transfers the charge to the surface where transfer is required. The device comprises a pair of rollers which are urged toward each other, one of the rollers having an insulator surface, the other roller forming an electrode, the charge being applied to the insulator surface on the one roller by means of a corona generating device spaced from the insulator surface and remote from the electrode roller.

Transferring xerographic images

A method for making an electrophotographic developer having developer particles suspended in an insulating carrier liquid comprising reactively producing the developer particles by placing into the carrier liquid at least two substances which are both soluble in the carrier liquid and are insulators relative to the carrier liquid and when in a dissolved state in the carrier liquid precipitate in the carrier liquid to form the developer particles. The developer particles are maintained in the carrier liquid so as to be shielded against oxidation until used as a developer.
