DEVELOPING DEVICE AND MANUFACTURING METHOD THEREOF

摘要

There is provided a method for manufacturing a developing device including a developer carrier having a rotation axis extending in a first direction, a blade and including a first end portion and a second end portion, and a supporting member supporting the blade. The method includes the steps of positioning the blade, and welding the blade onto the supporting member by irradiating a laser beam onto the blade while moving at least one of the blade and the laser beam relative to the other of the blade and the laser beam. The positioning includes positioning the first end portion in the first direction and a second direction perpendicular to the first direction, and positioning the second end portion in the second direction without being positioned with respect to the first direction. The welding includes moving the laser beam from a first end portion side toward a second end portion side.

主权项

1. A method for manufacturing a developing device, the developing device comprising: a developer carrier having a rotation axis which extends in a first direction; a blade disposed adjacent to the developer carrier and including a first end portion and a second end portion opposite to the first end portion in the first direction; and a supporting member supporting the blade, the method for manufacturing the developing device comprising the steps of:
positioning the blade with respect to the supporting member; and welding the blade onto the supporting member by irradiating a laser beam onto the blade while moving at least one of the blade and the laser beam relative to the other of the blade and the laser beam, wherein the positioning includes: positioning the first end portion of the blade with respect to the supporting member in the first direction and a second direction perpendicular to the first direction; and positioning the second end portion of the blade with respect to the supporting member in the second direction without being positioned with respect to the first direction, and wherein the welding includes moving the laser beam relative to the blade from a first end portion side of the blade toward a second end portion side of the blade.
