Developer conveyance member and corresponding support part configuration for developer container and developing device

摘要

A developer container may include a container body accommodating developer, a conveyance member, and a rotation member having a rotary shaft and an elastic part supported by the rotation member and configured to convey the developer. The container body may include a first support part to which the rotary shaft is loosely fitted, and a second support part that supports the rotary shaft. The container body may further include a sliding contact part that the elastic part sliding-contacts while being elastically deformed when the conveyance member is being rotated. In some examples, a distance from a center of the rotary shaft to a leading end of the elastic part gradually increases from the one end portion-side of the rotary shaft towards the other end portion-side of the rotary shaft.

主权项

1. A developer container comprising:
a conveyance member including a rotation member having a rotary shaft extending in a first direction, and an elastic part which is supported by the rotation member and is configured to be elastically deformed; a driving member that is connected to one end portion of the rotary shaft and is configured to rotate the rotary shaft; and a container body configured to accommodate therein developer, the container body including:
a first side wall including a first support part configured to support the other end portion of the rotary shaft, the first support part being configured such that the other end portion of the rotary shaft is movable a first distance in a second direction perpendicular to the first direction;a second side wall disposed apart from the first side wall in the first direction, the second side wall including a second support part configured to rotatably support the one end portion of the rotary shaft, the second support part being configured such that the one end portion of the rotary shaft is movable a second distance in the second direction, the second distance being shorter than the first distance; anda peripheral wall disposed between the first and second side walls, the peripheral wall including a sliding contact part that is provided in the vicinity of an upstream side in a rotating direction of the conveyance member with respect to an opening communicating an inside of the container body with an outside of the container body and that the elastic part slidingly-contacts while being elastically deformed when the conveyance member is being rotated, wherein a distance from an axial center of the rotary shaft to a leading end of the elastic part is gradually increased from the one end portion-side of the rotary shaft towards the other end portion-side of the rotary shaft.
