    摘要: A resin molding product of the present invention is a sandwiched molding product provided with a core layer and a skin layer having at least an electrophotographic toner. Further, it is preferable that the core layer contains an additive resin, which is compatible with a binder resin that is used for the electrophotographic toner and can give an elasticity to the core layer when the additive resin and the binder resin are dissolved with each other. According to the arrangement, it is possible to utilize as a raw material a nonstandard toner, which is produced during a manufacturing process of the electrophotographic toner, but cannot be used as a commercial product, and a discard toner, which has been used in an image forming apparatus of an electrophotographic method, thereby realizing a resin molding product of a high quality at a low cost, while the resin molding product can improve its impact resistance by use of the additive resin.

    摘要: An image processing apparatus includes a converter, a calculator and a reverse converter. The converter performs a frequency conversion operation on a color image signal which includes a brightness signal and color signals and divides values of each of the brightness signal and the color signals into high frequency coefficients and a low frequency coefficient. The calculator calculates the high frequency coefficients of the brightness signal and the color signals, generates a set of different high frequency coefficients, and produces a new brightness signal by adding the low frequency coefficient of the brightness signal to the set of different high frequency coefficients. The reverse converter performs a reverse frequency conversion operation on the new brightness signal.

    摘要: A developing apparatus includes a toner carrier for transferring toner to a development position, a layer-thickness regulating member for forming a toner layer having a predetermined thickness on the toner carrier by making contact in a leading edge or a surface of a vicinity of the leading edge with the toner carrier, and a supplier for supplying a one-component toner to the toner carrier. Also combined with the layer-thickness layer is a vibration absorbing device allowing the toner to be applied in a uniform thickness. The vibration absorbing device can also be a sealing member located on the toner carrier. Each sealing member can be two different materials effective to absorb vibration.
