摘要： A pattern forming device has a transfer unit which transfers a pattern image formed on a planographic plate held by a printing frame onto the surface of a glass plate held on an XY stage. After the glass plate and the planographic plate have been positioned by the XY stage, the transfer unit moves a stroke roller disposed on the rear surface side of the planographic plate in an arrow direction so that the stroke roller may be pressed against the planographic plate, thereby transferring the pattern image onto the glass plate by an electric field while, at the same time, stroking solvent components interposed between the planographic plate and the glass plate.

摘要： The present invention provides an image forming process, an image forming device, and a pattern forming process intended to obtain an image by developing a latent image which has been formed by exposing to light a photosensitive material including a photocatalytic layer which includes a photocatalyst and a hydrophobic layer applied on top of said photocatalytic layer, or a photosensitive material including a hydrophobic photosensitive layer which includes a photocatalyst and an organic compound, wherein the photocatalyst, when exposed to light, changes the angle of contact with water in the area on the surface of the photosensitive material which is exposed to light, thereby differentiating from the angle of contact with water in the area which is not exposed to light. The present invention also provides an image forming device and an image forming process which enable on-demand printing and reduce effects on health and environment, as well as a pattern forming process which is simple and reduces the effects on health and the environment.
