Heat-developable photosensitive material

A heat-developable photosensitive member for forming an electric printing master comprises a support, an organic silver salt layer containing an organic silver salt, a halide and a toning agent dispersed in a binder, and a surface protecting layer or a particular surface, and a reducing agent is contained in at least one layer of the organic silver salt layer and a layer adjacent to the organic layer.

Heat-developable photosensitive member for forming electrostatic

An improved heat-developable photosensitive material is disclosed which comprises an infrared rays-absorbing layer provided in contact with or adjacent to a layer comprising a reducible organic silver salt.

A liquid recording medium for recording by ejecting liquid droplets comprises (a) recording agent which is a component to form a recorded image; and (b) carrier liquid to dissolve or disperse said recording agent, a difference .DELTA.T between a decomposition temperature of a substance having the lowest decomposition temperature among the substances constituting the recording agent and a boiling point of said liquid recording medium, exclusive of said recording agent, being at least 30.degree. C.

Liquid recording medium

An image forming method comprises adding a development accelerator for accelerating the developing function at the time of the heat-development to a heat-development type photosensitive raw material containing therein at least an organic silver salt, a halide, and a binder, at the time when the image formation is to be carried out by the process steps of exposure and heat-development.

Image forming method

In an electrostatic printing process utilizing a printing master formed by exposing and heat developing a photosensitive element formed from a reducible organic silver salt, image forming capability is enhanced by a preheating of the image-forming member prior to said exposure and heat developing of the exposed image.

Electrostatic printing method

A master for electrostatic printing comprises a layer composed of conductive silver image portion containing metallic silver grains and a non-silver image portion having an electric resistance sufficient to retain electrostatic charge. The image formed by image light exposure and heating a layer including an organic silver salt compound, a reducing agent and an insulating medium.

Light and heat formation of conductive image printing plate

Electrostatic printing is conducted by using an electrostatic printing master composed of an insulating medium having an electric resistance sufficient to retain an electrostatic charge and conductive silver images carried in the insulating medium and heating the electrostatic printing master.
