An image forming method comprises the steps; subjecting a photosensitive material in the same layer to imagewise exposure and heating to form an image; and subjecting the resultant photosensitive material to whole areal exposure to polymerize and imagewise unexposed or exposed area thereof.

Abstract: A photosensitive material comprises a photosensitive and heat-developable element and a photopolymerizable element which are contained in the same layer. The photopolymerizable element comprises at least a polymerizable polymer precursor having a melting point of 35.degree. C. or more. The photosensitive material is exposed to light with at least one wavelength within the wavelength region of from 400 nm to 900 nm, heated at 60.degree. to 180.degree. C., and exposed to light with at least one wavelength within the wavelength region of from 250 to 700 nm, and thus an unexposed area in the photosensitive layer which is an area not exposed to light with at least one wavelength within the wavelength region of from 400 nm to 900 nm is polymerized.

Abstract: There is provided a method and apparatus for forming an image which includes providing a recording composition capable of changing its adhesivity corresponding to the polarity of a voltage applied thereto between a pair of electrodes. The recording composition has a transfer characteristic having a tendency to change by loss of at least one component of the recording composition. A voltage is applied between the pair of electrodes to attach the recording composition to one of the pair of electrodes to attach the recording composition to one of the pair of electrodes. Any such change in the transfer characteristic of the recording composition is detected during the process. In response to any change in the transfer characteristic additional component is added to the recording composition to compensate for that change.

Abstract: A photosensitive material and comprises a photosensitive and heat-developable element and a polymer, and is capable of being endowed with stickness by a change of pH value or being subjected to exposure and heating. An image formation process comprises the steps of subjecting to imagewise exposure the photosensitive material, heating the photosensitive material, electrifying the photosensitive material, and transferring the iamgewise exposed or unexposed portion of the photosensitive material. The photosensitive and heat-developable element comprises a least a photosensitive silver salt and a reducing agent and the polymer has a cross-linked structure.

Abstract: A photosensitive material comprises a photosensitive layer and a polymerizable layer which are laminated. An area of the polymerizable layer, corresponding to an unexposed area of the photosensitive layer, is polymerized when the photosensitive material is exposed to light with a wavelength of 400 to 900 nm and heated to 60.degree. to 80.degree. C.

Abstract: A toner suitable for developing electrostatic images is produced through a process comprising: dispersing a monomer composition comprising at least a polymerizable monomer and a colorant in an aqueous medium heated at a temperature higher than a polymerization temperature, thereby to form particles of the monomer composition; adjusting the aqueous medium to the polymerization temperature; and adding a substantially water-insoluble polymerization initiator to the aqueous medium containing the particles of the monomer composition dispersed therein and adjusted to the polymerization temperature, thereby to cause the polymerization of the polymerizable monomer. According to this process, a toner containing a large amount of a low-softening point compound and having good fixability at low pressure and/or low temperature can be produced while retaining good anti-blocking characteristic and fluidity.
