Abstract
PURPOSE: To obtain stirring blades which are straight, are high in mechanical strength and are good in stirring and conveying performance by forming the stirring blades in which the directions of the mutually adjacent spiral blades are differed into one body in the dry type developing device on an electrophotographic copier.
CONSTITUTION: In an illustrated stirring blade manufacturing device, an integral shaft 1 of aluminum or the like having two sheets of blades 2, 2 in a section 180° direction is firmly held by the chuck members 5, 5 fixed in the predetermined position on a stand. Thence, a gear 6 is fixed onto the shaft 1 by the chuck provided to the gear 6 and is then applied with rotational driving force, whereby 360° of rotation is given to the gear 6. This causes part of the illustrated stirring blades to be formed and if this process is repeated, the stirring blades having the reverse facing stirring blades on one shaft may be obtained. Since the developer is moved while being stirred in the opposing directions respectively of the spiral blades by these stirring blades, the developer is uniformly supplied onto a sleeve member 4.
