Developing device, blade unit, and developing device manufacturing method

摘要

Aspects include an apparatus, a blade assembly, and a method for manufacturing the apparatus with the blade assembly. The apparatus may include a developer carrier for carrying developer and a blade assembly. The blade assembly may include a blade disposed adjacent to the developer carrier and configured to regulate an amount of developer on the developer carrier. The blade may include a plurality of weld marks joining the blade to the supporting member. Each of the plurality of weld marks may overlap with an adjacent one of the plurality of weld marks. Together the weld marks may form a combined weld mark that extends in a direction that the blade extends.

1. An apparatus, comprising:
a developer carrier configured to carry developer thereon and having a rotation axis; a blade disposed adjacent to the developer carrier and configured to regulate an amount of developer on the developer carrier; and a supporting member configured to support the blade, wherein the blade comprises a plurality of weld marks which are arranged in a direction parallel to the rotation axis of the developer carrier and join the blade to the supporting member, wherein an edge of at least one of the plurality of weld marks intersects an edge of an adjacent one of the plurality of weld marks, and wherein the plurality of weld marks form a combined weld mark that has a dimension of 0.1 to 250 mm in an alignment direction that the plurality of weld marks are aligned, and a dimension of 0.1 to 6.0 mm in a direction perpendicular to the alignment direction.
