搅拌输送部件、具备该部件的显影装置以及图像形成装置
摘要：
本发明提供搅拌输送部件以及具备该搅拌输送部件的显影装置和图像形成装置。所述搅拌输送部件具有：旋转轴，可旋转地支撑在粉体容器内；第一螺旋叶片，形成于旋转轴的外周面，通过旋转轴的旋转将粉体输送向轴向；以及第二螺旋叶片，与第一螺旋叶片的形成区域重叠地形成于旋转轴的外周面，与第一螺旋叶片相位相反且径向高度比第一螺旋叶片低。第一螺旋叶片在绕旋转轴一周之间至少在一处与第二螺旋叶片交叉。第一螺旋叶片以及第二螺旋叶片的至少一方在第一螺旋叶片以及第二螺旋叶片的交点处的径向高度为0。
摘要（英）：

The invention provides a stirring/conveying member, and a developing device and an image forming apparatus therewith. The stirring/conveying member has a rotary shaft rotatably supported in a powder container, a first helical blade formed on the circumferential surface of the rotary shaft and conveying powder in the axial direction by the rotation of the rotary shaft, and a second helical blade formed on the circumferential surface of the rotary shaft to overlap the forming region of the first helical blade, spiraling in the opposite phase to the first helical blade, and having a smaller radial height than the first helical blade. The first helical blade crosses the second helical blade at least at one place in one turn about the rotary shaft. At least one of the radial heights of the first and second helical blades equals zero at the intersection of the first and second helical blades.
