Drive transmission structure, developer transport device, and image forming apparatus
First Claim
1. A developer transport device comprising:
- a developer transport member having a transport portion and a driven shaft, the transport portion being formed in the developer transport member and transporting a developer, the driven shaft having a drive receiving gear attached to the driven shaft and a first shaft portion near the drive receiving gear, a rotational force being transmitted to the drive receiving gear;
a transport pipe having a transport space formed in the transport pipe, the transport space housing at least part of the developer transport member, the transport portion being formed in the part of the developer transport member, the developer being transported through the transport space;
a drive shaft having a drive transmitting gear attached to the drive shaft and a second shaft portion near the drive transmitting gear, the drive transmitting gear being engaged with the drive receiving gear so as to transmit the rotational force; and
a bearing member having a first bearing and a second bearing, the first bearing supporting the first shaft portion, and the second bearing supporting the second shaft portion,wherein, the axis of the drive shaft does not intersect and is non-parallel to the axis of the driven shaft of the developer transport member, andwherein the first bearing and the second bearing are integrally formed with the bearing member, andwherein the second bearing is arranged on an outer side of the drive transmitting gear in a drive transmitting direction along an axis direction of the drive shaft.

Abstract
A drive transmission structure includes a driven shaft, a drive shaft, and a bearing member. The driven shaft has a drive receiving gear attached thereto and a first shaft portion near the drive receiving gear, to which a rotational force is transmitted. The drive shaft has a drive transmitting gear attached thereto and a second shaft portion near the drive transmitting gear. The drive transmitting gear is engaged with the drive receiving gear so as to transmit the rotational force. The bearing member has a first bearing and a second bearing, which respectively support the first shaft portion and the second shaft portion. In the drive transmission structure, the axis of the drive shaft does not intersect and is non-parallel to the axis of the driven shaft, and the first and second bearings are integrally formed with the bearing member.
