Abstract
A blade member manufacturing process using no mold and a developer quantity control blade manufacturing process using this blade member are disclosed in which a material for the blade member is extruded onto a charge control face face-transferring sheet in a uniform thickness, and solidified to form a layer, and the layer is cut into the shape of a blade member.
Claims15
A process for manufacturing a blade member of a developer quantity control blade which controls the quantity of a developer carried out of a developer container through a developer-carrying member;
- the process comprising the steps of:
- extruding a material for the blade member onto a charge control face face-transferring sheet in a uniform thickness, followed by solidification to form a layer;
- and
- cutting the layer into the shape of the blade member.
A process for manufacturing a blade member of a developer quantity control blade which controls the quantity of a developer carried out of a developer container through a developer-carrying member;
- the process comprising the steps of:
- co-extruding a molten resin for forming a charge control face face-transferring sheet and a molten resin for forming a blade member, followed by shaping into a cylinder by multi-layer blown-film extrusion;
- cutting the cylinder in parallel to the direction of extrusion to form at least one multi-layer sheet having a blade member resin layer;
- and
- cutting the multi-layer sheet at least at the blade member resin layer into the shape of the blade member.
A process for manufacturing a developer quantity control blade which controls a quantity of a developer carried out of a developer container through a developer-carrying member;
- the process comprising the steps of:
- extruding a material for a blade member onto a charge control face face-transferring sheet in a uniform thickness, followed by solidification to make a blade member;
- laminating a supporting member to the blade member on its side not serving as the charge control face, to form a laminate;
- and
- cutting the laminate into the shape of a developer quantity control blade as a final shape.
