Inventor: OTA ATSUSHI
IPC: G03G15/08
Filed: 1993-12-16
Abstract: PURPOSE:To obtain an inexpensive developer carrying body which does not cause fixing of a developer due to bleeding of a softening agent by controlling the polymer and the softening agent for the body in such a manner that the difference of SP values between the polymer and the softening agent is smaller than the difference of SP values between the softening agent and the resin which constitutes a developer. CONSTITUTION:A surface layer 1b comprising a rubber elastic material is formed on a core material 1a such as iron and aluminum, and then the surface is polished to obtain a developer roller l as a cylindrical developer carrying body. The surface layer 1b of the developer roller 1a consists of butadiene as the base polymer and a paraffin-base processed oil as a softening agent. These materials are controlled in such a manner that the difference of SP values between these is smaller than the difference of SP values of polystyrene of the toner resin and the paraffin-base processed oil. Thereby, since the compatibility between the processed oil and the butadiene is higher than the compatibility between the processed oil and the polystyrene, the process oil as a softening agent does not bleed out from the rubber of the surface layer J9 even in a toner atmosphere and the roller maintains a stable state.

Title: Picture extracting device
Inventor: MATSUGI MASAKAZU
IPC: G06T9/20
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To hardly receive the influence of the luminance level of background at the time of extracting a specific picture or its outer outline from an optional background. SOLUTION: A setting means 4 sets the size of an initial outline area extracted by the extraction means 3 from the standard picture of a picture database 2 on an inspection picture from a picture input part 1. Next an updating means 5 deforms and moves the outline area through the use of an evaluation function by setting a chrominance component to be a parameter. Then when a convergence judging means 54 judges convergence based on the evaluation function, a picture output means 6 outputs a picture within the outline area. Thereby it is possible to extract the outline and to extract (segment) the picture within the outline by automatically reflecting the difference of texture structure in a background area adjacent to the texture structure of an objective picture area.
