Title: Image forming device
Inventor: HASEGAWA YUJI
IPC: G03G15/00
Filed: 1984-10-02
Abstract: PURPOSE:To make possible cooling by a simple means by sucking air from the outside of an image forming machine by the suction force of a suction device provided to a sheet material conveying part and cooling a heat holding body. CONSTITUTION:A photosensitive drum 1 is uniformly electrostatically charged by a primary charger 2, then an electrostatic latent image is formed by image exposing thereon. Said image is developed to a visible image by a developing device 3 and is transferred onto the paper fed by passing through a paper guide 5. The paper is separated from the drum 1 and rises on a conveying pat 10 where the paper is attracted onto a belt 11 by a conveying fan 12 so as to be fed to a fixing device 13. A conveying fan 15, a chamber 16 to cover the fan 15 and a louver 17 of the cover are provided to the conveying part. The chamber 16 has a wide aperture 19 on the belt 11 side. When the paper is on the belt 11, the paper is attracted to the belt 11 through the aperture 19 of the chamber 16 by which the aperture 19 is covered. Air flow 18 is then created by the fan 15 and the inside of the chamber 16 is evacuated. When there is no paper, the fan 15 sucks the air in the device through both of the aperture 19 and notch 27. The sucked air is discharged to the outside, by which the inside of the device is cooled.

Abstract: PURPOSE:To prevent the generation of heat and the occurrence of a ringing phenomenon, and to make it possible to conduct a direct winding by a method wherein a low iron loss ferrite layer is formed on the center part of a core and a high resistance ferrite layer is formed on the surface part of the core. CONSTITUTION:The composition of the center layer of the title ferrite core is adjusted in the range of 52.5 to 54.5mol% Fe2O3, 31 to 38mol% MnO and 8 to 15mol% ZnO. In the case of Mn-Zn ferrite in the above-mentioned range of composition, the low iron loss of 1000mw/cm<2> or less can be secured, and the heat generated on the core can also be suppressed low. On the other hand, the composition of the surface layer is adjusted in the range of 20 to 40mol% MgO, 15 to 25mol% ZnO, 0 to 10mol% MnO and the remaining part consisting of Fe2O3. The Mn-Mg-Zn ferrite in the range of the above-mentioned composition gives the high resistance (10<5> to 10<8>OMEGA/cm), which is in the range where a direct winding can be performed, is given to the core, and also the relative permeability (1 to 10), which is sufficient to suppress a ringing phenomenon, is given to the core. As a result, a ferrite of low iron loss, high permeability and high resistance can be obtained, thus heat generation and a ringing phenomenon can be prevented, and direct winding to the core can be conducted.
