Abstract

See full text

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 weld mark joining the blade to the supporting member. A first dimension of the weld mark in a first direction may be greater than a second dimension of the weld mark in a second direction perpendicular to the first direction, and a third dimension of the weld mark in a third direction may be a dimension of the thickness of the blade. The weld mark may be formed by irradiating a laser beam onto the blade while moving the laser beam or the blade.
