Abstract: PURPOSE:To prevent a leakage of operation gas while preventing generation of a pressure pulsation of an oil pouring route by providing plural oil pouring ports whose bore is smaller than that of the lapping width of movable scroll at the oil pouring positions of a fixed scroll. CONSTITUTION:Plural oil pouring ports 20 whose bore is smaller than the lapping width of a lap 3b are provided at the oil pouring positions of a fixed scroll 2 towards the width direction of the lap 3b extending the range wider than the lapping width of the lap 3b. As a result, since all the oil pouring ports 20 are never blocked simultaneously by the lap 3b, but one or more ports of the plural ports 20 are opened, a pressure pulsation generated on an oil pouring route can be suppressed. Furthermore, since one oil pouring port 20 is never opened to the two operation chambers 14 and 15 holding the lap 3b at a time, the leakage of operation gas from one side operation chamber 15 to the other side operation chamber 14 through the oil pouring ports 20 can be suppressed, even in the case of operation under the condition of low differential pressure.

Title: Device for use in both cleaning and electrifying and image forming device using the same
Inventor: SUZUKI TADAHIRO
IPC: G03G15/02
Filed: 1998-04-09
Abstract: PROBLEM TO BE SOLVED: To prevent the contact part of a blade with a photoreceptor from being curled and damaged even when a voltage is applied to the blade. SOLUTION: In the blade 24, a backing part 27 is made of a conductive material, and onto its front-end face 27a a discharge restriction member 28 for restricting discharge is affixed a specific distance L apart from a contact point (a). Accordingly, because most of the front-end face 27a is covered with the discharge restriction member 28, discharge from the front-end face 27a of the blade 24 can be restricted even when a voltage is applied to the blade 24. Therefore, toner Tn in the vicinity of the contact point (a) between the blade 24 and photoreceptor 1 is prevented from being repelled by an electric field generated near the front end of the blade 24.
