Title: Method and device of image forming
Inventor: SEKINE TAKEYOSHI
IPC: G03G21/00
Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To obtain a method of image forming and an image forming device which can reliably reduce the amount of developer deposition from each developing device to the non-imaging part of an image carrier in the method of image forming and the image forming device which form images by moving a plurality of developing devices to a developing position being a counter position to the image carrier. SOLUTION: A sensor for detecting the amount of toner deposition detects the amount of toner deposited on the non-imaging area of a photosensitive drum at the timing the value of the direct current developing voltage Vdc changes from Vb to Vbr and at the timing it changes back from Vbr to Vb. Thus, by detecting the amount of the toner, the amount of toner deposition during contact and the amount of toner deposition during separation are measured. When the measured values Vs-k, Vs-c outputted from the sensor for detecting the amount of toner deposition exceed the allowable limit of the output value Vs-k0, Vs-c0, a voltage Vbr for moving is increased to the side of a polarity which can form an electric field to make the movement of the toner to the photosensitive drum side difficult.

Abstract: PROBLEM TO BE SOLVED: To smoothly circulate lubricating oil, regardless of porosity of a bearing, by providing a blade on an outside surface of an oil snap ring revolving integrally with a rotary shaft and forming an impeller of a centrifugal fan. SOLUTION: Lubricating oil oozes out to a sliding surface of an oil-retaining sintered bearing 30 by revolution of a rotary shaft 10 and performs a lubricating action. A part of lubricating oil oozes out along the rotary shaft 10, but lubricating oil is interrupted on an inside face of an oil snap ring 20, is swung by centrifugal force due to the oil snap ring 20 and is stuck to an inner peripheral surface 51 of an oil keeping material 50. The oil snap ring 20 functions as an impeller of a centrifugal fan in a blade 21 of the outer peripheral surface and blows outside air sucked from a gap between the rotary shaft 10 and a cover 44 to the inner peripheral surface 51.  Atmospheric pressure within a casing is increased, pressure is applied to the oil keeping material 50 and an end face of the bearing 30, lubricating oil stuck to the inner peripheral surface 51 is more quickly sucked than a case of only a capillarity and also circulation from the oil keeping material 50 to the bearing 30 is promoted. As a result, oil collection to circulation is further quickly and surely performed in cooperation with the capillary action.
