Abstract: A surface treatment method of oil contaminated xerographic prints which increases the surface energy of the print to levels close to the values corresponding to the original uncontaminated paper. Subjecting the contaminated surface to both ultraviolet (UV) radiation and ozone can change the chemical structure of the surface of the paper in such a way that a highly polar surface is created as a consequence of this treatment, leading to enhanced adhesion properties of the xerographic print.

Abstract: An image forming apparatus and a control method thereof are provided that determine a final contrast potential taking into consideration not only the relationship between the contrast potential of an electrostatic latent image and the density value of a developed image but also a toner charge amount for developing the electrostatic latent image. To accomplish this, the image forming apparatus of the present invention predicts, in advance, the contrast potential of the electrostatic latent image and the density of the toner image at the contrast potential for a predetermined toner charge amount. Furthermore, the image forming apparatus forms an image by adjusting the relationship between the contrast potential and density measured in advance based on a current toner charge amount and a saturation toner charge amount when forming the image.

Abstract: In an image forming apparatus, an image forming contrast potential for obtaining the maximum density is set by reading a specific pattern transferred and formed on a sheet. A photosensor detects the density of a specific pattern formed on an image carrier at the image forming contrast potential, and the detection result is stored. A correction amount for the image forming contrast potential is calculated on the basis of the relationship between the stored detected density, and the density, detected by the optical sensor, of the specific pattern formed on the image carrier at a predetermined timing. The image forming contrast potential is adjusted by the correction amount.

In this method for the production of a film, toner is first applied to a transport belt with the use of at least one printing unit in such a manner that an essentially uninterrupted toner layer is formed on the transport belt. The toner on the transport belt is then heated with at least one first heat source to a temperature above a melting point of the toner and is subsequently cooled to below the melting point of the toner. Finally, the toner is removed from the transport belt as a cohesive material layer. The device comprises a transport belt, at least one printing unit arranged for applying a toner to the transport belt, and at least one heat source. Viewed in a direction of movement of the transport belt, the heat source is arranged downstream of the at least one printing unit in such a manner that said heat source is able to heat the toner present on the transport belt and that said heat source is suitable to heat the toner to a temperature above a melting point of said toner.
