CONVEYING MEMBER AND DEVELOPER CONTAINER

PROBLEM TO BE SOLVED: To provide a resin-made conveying device that is easily obtained by integrally molding using a mold. SOLUTION: The spiral conveying member 23 includes two portions, one of which is a first portion 231 formed in a spiral curved face and the other of which is a second portion 232 composed of a flat face. In the spiral conveying member 23, the second portion 232 and first portion 231 are discontinuously connected. The second portion 232 is adjusted so that the z-components of the two points of the diagonal lines of the second portion 232 satisfy a predetermined condition. Thereby, even if a solid V1 is cut by a plane containing the two points, the two separate solids do not bite each other in the directions in which they are pulled out. Therefore, they can be pulled out suitably from the spiral conveying member 23. COPYRIGHT: (C)2009,JPO&INPIT
