Title: Image forming device
Inventor: YASUDA KAZUO
IPC: G03G21/00
Filed: 1987-04-07
Abstract: PURPOSE:To eliminate the reduction of the image density and a phenomenon of fogging by providing a control means, etc., for operating an electrifier by turning on a main power source switch, and also, rotating an image forming body by the speed of revolution set in advance. CONSTITUTION:When a main power source switch 4 is turned on, its turn-on signal is applied to a control means 1. When the turn-on signal arrives, this means 1 sends a control signal for rotating an image forming body 2 by the speed of revolution set in advance, to a rotation driving source 6 for driving to rotate the image forming body 2. Also, the means 1 controls a high voltage power source 5 for supplying a high voltage for electrification to an electrifier 3, so that the high voltage is supplied to the electrifier 3 in accordance with a rotation of the image forming body 2. In such a way, the image forming body 2 is subjected to a prescribed electrifying action before going into an image forming operation after the switch 4 is turned on. As a result, at the time point of going into the image forming operation, the electrifying function is recovered, and the density reduction of an image and the fogging are not generated.

Abstract: PROBLEM TO BE SOLVED: To prevent the influence of constituents other than a substrate that coexists in an organism constituent by applying a voltage between the operation electrode and the counter electrode of a bio sensor for a specific amount of time and detecting a current response. SOLUTION: In a quantitative method, a bio sensor with an electrode system that consists of an operation electrode 4 and a counter electrode 5 being formed on an electrically insulated substrate 1 and a reaction layer 8 containing at least an oxidation reduction enzyme and an electron receptor is used. Then, the change in a substance concentration when a substrate in a sample reacts with the oxidation reduction enzyme and the electron receptor can be detected based on a current response being obtained by applying a voltage between the operation electrode 4 and the counter electrode 5.  The voltage is applied for one second or more and less than five seconds, and a current response after this amount of time is detected, thus eliminating a problem where the response characteristics of a sensor differ due to the difference between men and women and the difference in the amount of red cells due to a personal difference even if the concentration of substrate in blood is the same in the bio sensor.
