Abstract: An image recording apparatus includes an image carrying part, a developing part and an image transferring part. The image carrying part has a surface on which an electrostatic latent image is formed. The developing part develops the electrostatic image into a toner image by selectively applying toner to the surface of the image carrying part. The image transferring part transfers the toner image onto a recording sheet or an intermediate image transferring part. Fine particles are uniformly formed on the surface of the image carrying part, and a portion of the fine particles is transferred from the image carrying part with the toner image.

Abstract: Disclosed is a method and apparatus for pyrolytically decomposing waste plastic which may contain halogen-containing polymer such as PVC. The plastic is heated at 270° to 350° C., whereby a plasticizer contained in the plastic material is decomposed and vaporized, and a chlorine-containing polymer is dechlorinated to produce hydrogen chloride. The vaporized decomposition matter and the hydrogen chloride are removed from the plastic, and the vaporized decomposition matter is separated from the hydrogen chloride. Then isolated plastic is further heated to 450° C. or higher to produce a pyrolysis product. Alternatively, the former heating step is divided into two steps of: heating at a temperature lower than 270° C., whereby a plasticizer is decomposed; and heating to 270° to 350° C., whereby a chlorine-containing polymer contained in the plastic material is dechlorinated. Accordingly, the decomposition matter of plasticizer and hydrogen chloride are separately removed from the plastic.

Abstract: Disclosed is a method and an apparatus for pyrolytically decomposing waste plastic, e.g. PVC, to recover light fuel oil. The invention enables to prevent the product from contamination by halogen compounds. The plastic is first thermally decomposed in an atmosphere of a normal or reduced pressure to produce a primary decomposition product in the form of gas and a decomposition residue. The primary decomposition product is cooled at a first cooling temperature to separate the primary decomposition product into a relatively light fraction containing a desired light constituent and a relatively heavy fraction by condensation of the relatively heavy fraction, and the relatively heavy fraction is then thermally decomposed in an atmosphere pressurized at a predetermined pressure to produce a secondary decomposition product containing the desired light constituent in the form of gas.
