Transporting member, developing device, and image forming apparatus

摘要

A transporting member includes multiple helical blades that helically extend around a rotation shaft and that have an upstream-side blade and a downstream-side blade, an end portion of the upstream-side blade and an end portion of the downstream-side blade overlapping in a direction perpendicular to an axial direction of the rotation shaft, the multiple helical blades transporting an object in the axial direction via rotation of the rotation shaft; a gap portion that divides the upstream-side blade and the downstream-side blade, the upstream-side blade and the downstream-side blade being arranged at a certain angular interval in a circumferential direction of the rotation shaft; and a regulating portion that regulates an amount of the object that passes through a space between the upstream-side blade and the downstream-side blade in a direction in which the object is transported.

主权项

1. A transporting member comprising:
a plurality of helical blades that helically extend around a rotation shalt, the plurality of helical blades having an upstream-side blade and a downstream-side blade, an end portion of the upstream-side blade and an end portion of the downstream-side blade overlapping in a direction perpendicular to an axial direction of the rotation shaft, the plurality of helical blades configured to transport an object in the axial direction via rotation of the rotation shaft; a gap portion that divides the upstream-side blade and the downstream-side blade, the upstream-side blade and the downstream-side blade being arranged at a certain angular interval in a circumferential direction of the rotation shaft; and a regulating portion that regulates an amount of the object that passes through a space between the upstream-side blade and the downstream-side blade in a direction in which the object is transported, wherein a distance, in a direction perpendicular to the rotation shaft, between an outer surface of the regulating portion and an outermost portion of the upstream-side blade and the downstream-side blade being smaller than a distance, in the direction perpendicular to the rotation shaft, between the rotating shaft and the outermost portion of the upstream-side blade and the downstream-side blade, and wherein an end surface of the regulating portion is disposed between the end portion of the upstream-side blade and the end portion of the downstream-side blade overlapping in the direction perpendicular to the axial direction of the rotation shaft.
