Method of attaching regulating blade and development apparatus

A method of attaching a regulating blade made of resin to an attachment portion of a development frame which is made of resin and includes the attachment portion for attaching the regulating blade, the regulating blade being disposed opposite to and not in contact with a development rotary member configured to bear and convey a developer toward a position at which an electrostatic image formed on an image bearing member is developed, the regulating blade being configured to regulate an amount of the developer to be borne on the development rotary member, the method of attaching the regulating blade comprising:

• a first application step of applying an adhesive to the regulating blade;
• a second application step of applying a hardening accelerator to the attachment portion;
• and
• an attaching step of attaching the regulating blade to the attachment portion via the adhesive applied to the regulating blade in the first application step and the hardening accelerator applied to the attachment portion in the second application step.

A development apparatus comprising:

• a development rotary member configured to bear and convey a developer toward a position at which an electrostatic image formed on an image bearing member is developed;
• a regulating blade made of resin and disposed opposite to and not in contact with the development rotary member, the regulating blade being configured to regulate an amount of the developer to be borne on the development rotary member;
• and
• a development frame made of resin and including an attachment portion for attaching the regulating blade,
• wherein the regulating blade is bonded to the attachment portion via an adhesive and a hardening accelerator.
