An image forming apparatus includes: an exposure head including a light emitting portion that includes a first electrode layer including a plurality of electrodes that are two-dimensionally arranged in a rotation direction and a rotational axis direction of a photosensitive member, a light emitting layer stacked on the first electrode layer, and a second electrode layer through which light is transmissible; and a controller configured to control a voltage applied to each of the plurality of electrodes in such a way that one pixel is formed by controlling the voltage applied to the plurality of electrodes arranged at different positions in the rotation direction, in which the plurality of electrodes are arranged in such a way that a pitch of the plurality of electrodes included in the first electrode layer in the rotation direction is an integer multiple of a resolution of an image formed by the image forming apparatus in the rotation direction, excluding an equal multiple.

Methods for producing, from hydrophilic carbon black particles and at least one curable hydrophobic silicone pre-polymer, elastomeric compositions comprising dispersed carbon black particles, as well as their corresponding cured products. Once the curing process has taken place, such compositions can be used for the preparation of numerous articles of wide industrial applicability.

A printing system is disclosed for thermal transfer printing onto a surface of a substrate. The system comprises a transfer member having opposite front and rear sides with an imaging surface on the front side, a coating station at which a monolayer of particles made of, or coated with, a thermoplastic polymer is applied to the imaging surface, an imaging station at which energy is applied by a thermal print head via the rear side of the transfer member to selected regions of the imaging surface to render particles coating the selected regions tacky, and a transfer station at which the imaging surface of the transfer member and the substrate surface are pressed against each other to cause transfer to the surface of the substrate of the particles that have been rendered tacky.

There is disclosed a layered article that can be used in indirect printing, in analog or digital processes. The layered article, when configured as a transfer member, may serve to receive an ink in any form, allow the ink to be treated so as to form an ink image, and permit the application of the ink image on a substrate. The transfer member comprises a support layer and an imaging layer, which may be formed of a silicon matrix including dispersed carbon black particles. Methods for preparing the same are also disclosed.

An image forming apparatus includes an exposure head having an odd number of chips in each of which a plurality of light emitting elements configured to expose a photosensitive member are arrayed at intervals corresponding to a first resolution in an intersecting direction intersecting with a rotation direction of the photosensitive member. An even number of chips of the odd number of chips are arranged on one side of the printed circuit board in the rotation direction, and a remaining odd number of chips of the odd number of chips are arranged on another side of the printed circuit board. A center of an intensity of a light amount of the odd number of chips in the rotation direction is shifted to a side of the even number of chips with respect to a center of the printed circuit board in the rotation direction.

A system and method for selective heating and/or sintering of a material including first and second substrates, an array of one or more resistive heating elements arranged on a planar surface of a substrate and material to be heated located on the other substrate.

Method and system for thermal transfer printing are disclosed. The system includes a transfer member having an imaging surface on the front side, a coating station at which a monolayer of particles made of, or coated with, a thermoplastic polymer is applied to the imaging surface, an imaging station at which electromagnetic radiation (EM) is applied via the rear side of the transfer member to selected regions of the particles-coated imaging surface to render the particles thereon tacky within the selected regions, and a transfer station at which only the regions of the particles coating that have been rendered tacky are transferred to a substrate.
