A recording apparatus includes a recording head for performing recording on recording paper, the recording head having three or more types of inks of different densities but of the same color. A combination of the inks used to record a pixel of a grayscale image, which is to be recorded on the recording paper, is decided based upon the pixel by a data distribution unit which refers to ink density data and combination data. Recording by the recording head is controlled, based upon the combination of inks decided, by a unit which controls the recording head and paper feed.

In the image-recording of an intermediate transfer system applying an ink jet recording method, reactive liquid reactable with ink is properly formed on the intermediate transfer body. By using the intermediate transfer body having a pattern consisting of lyophilic and lyophobic sections on a surface thereof, the reactive liquid is uniformly applied to the intermediate transfer body to form a layer having a suitable thickness. Thereby, it is possible to form an ink image on the intermediate transfer body while preventing the miss landing of ink droplets and restricting the deformation of an ink dots. By transferring this ink image to a recording medium, it is possible to form a high-quality ink image on various kinds of recording media in a stable manner.

A portable fence is practically easy and fast to be installed along the boundary of a keep-off area to restrict and entry of the unconcerned at construction or events-holding sites and is conveniently compact to carry and store due to its foldability. This fence comprises a conjunction screen formed by connecting a plurality of fence components, preferably formed of synthetic resin by blow molding, side by side through a hinge mechanism such that they are foldable to each other and a support means or stay pivotably mounted onto a lower fringe portion of said conjunction screen, and stably provides a restricted area at a site where an access of the unconcerned is restricted in an easy and fast manner and is convenient to carry and store due to its foldability. The addition of a weight container thereto further enhances the standing stability thereof.

An image is formed by subjecting to imagewise exposure an image forming medium containing at least a heat-diffusible coloring matter, a photosensitive silver halide, an organic silver salt, a reducing agent, a polymerizable polymer precursor and a photopolymerization initiator; heating the image forming medium thus treated; subjecting it to polymerization exposure to form a polymerized area and an unpolymerized area in the image forming medium; separating the polymerized area from the unpolymerized area; and superposing an image receiving medium onto the unpolymerized area to transfer the heat-diffusible coloring matter in the unpolymerized area to the image receiving medium.
