Abstract: PURPOSE:To obtain a developing device and an image forming device which are made small in size, light in weight and inexpensive, by which high image quality is obtained, and where the scattering of developer is not caused even though printing is consecutively performed. CONSTITUTION:A recovery blade 37 is brought into contact with a developing roller 33 which can be driven to be rotated and supplies one component toner T to a part to be developed at a position on a downstream side from the position of the part to be developed with respect to the rotating direction of the roller 33, and voltage having the same polarity as the roller 33 and equal to or above that of the roller 33 is impressed on the blade 37. Thus, the degree of electrostatic floccuration of the toner T on the roller 33 is controlled, and the difference of charge between a printing part and a non-printing part is eliminated, thereby uniformizing the charge of the toner T. Then, the toner T is not scattered even though the consecutive printing is performed, and excellent developing without causing history by a previous printing pattern is achieved.

Title: Semiconductor device
Inventor: KINOSHITA KATSUYUKI
IPC: H01L29/78
Filed: 1980-10-06
Abstract: PURPOSE:To eliminate the influence on a charactersitic of electromotive force caused by a back-surface diffused layer and to improve thereby a yield rate, by forming a phosphorus diffusion layer in a part of the back surface of a silicon substrate wherein MOSFET is formed. CONSTITUTION:Diffusion of phosphorus for gettering is conducted selectively in  the back surface of the silicon substrate 1 wherein N-channel MOSFET is formed, whereby a phosphorus diffusion region 2 is formed. A region 9 wherein the diffusion of phosphorus is not conducted and a stage 4 for measurement contact with each other in an ohmic fashion. The gettering effect is sufficient if there is the phosphorus diffusion region of 40% or more in one chip. Since the substrate 1 and the stage 4 contact with each other directly, the variation of the characterisitc due to the electromotive force of PN junction is not caused between the characteristic value in the state of a wafer and that after assembling, and thus the yield rate of the device can be raised.
