Filed: 1982-05-19
Abstract: PURPOSE:To reduce the consumption of grinding materials to reduce the running cost, by detecting points of time when the grinding treatment of an image carrier is required and executing the grinding treatment only at these points of time. CONSTITUTION:A pair of electrode plate faces 102 and 103 are exposed at an interval on the front end face of an insulating high polymer material body 101, and this front end face of the body is pressed to a face where the surface resistance should be measured, and the surface resistance is detected by the quantity of current flowed between electrode plates 102 and 103 through the face to be measured. Since the surface of a drum 1 as the image carrier is damaged if said front end face of the body 101 is pressed to the surface of the drum during the rotation of the drum 1, said front end face of the body 101 is separated from the surface of the drum and is set to the escape state by a contacting/ separating mechanism while the drum 1 is rotated, and said front end face of the body 101 is pressed to the surface of the drum 1 to measure the surface resistance of the drum 1 when the rotation of the drum 1 is stopped. In case that a pair of contacting electrodes 102 and 103 for the face to be measured are formed into rotating rolls, roll electrodes 102 and 103 are always pressed to the surface of the drum 1 and are rotated while following up the rotation of the drum 1 to measure and detect the surface resistance of the drum continuously in real time even during the rotation of the drum.

Filed: 1989-04-04
Abstract: PURPOSE:To directly record a character and a picture on ordinary paper, etc., by applying a second component which acts with a first component and colors to any medium, superimposing a sensitized/pressure-sensitive medium on a second medium and pressing them. CONSTITUTION:When an exposing means 108 selectively irradiates the light/ pressure sensitive medium 107 carrying a microcapsule containing the first component with light according to information conveying a character, a graphic, etc., the dynamic strength of the irradiated microcapsule is changed. A developer which acts with the component included in the microcapsule and colors is applied to a medium such as a copy paper 117 to produce the second medium, and the sensitized/pressure-sensitive medium 107 exposed by a pressure applying means 127 is superimposed on the second medium to be pressed, thereby breaking a microcapsule with lower mechanical strength. Consequently, the first component included in the microcapsule acts with the developer on the surface of the second medium to discolor the surface of the second medium, which is recorded. Thus, the character and the graphic are directly recorded on the ordinary paper.
