Developing device and process cartridge

A process cartridge removably mounted in an apparatus body of an image forming apparatus, the process cartridge comprising:

• an image bearing member on which a latent image is to be formed;
• a rotatable developing-agent bearing member configured to bear developing agent for developing the latent image;
• a developing container configured to form a developing-agent storage chamber that stores the developing agent;
• a developing-agent regulating portion provided in the developing container to regulate an amount of the developing agent born on the developing-agent bearing member;
• a support portion configured to support the developing-agent bearing member moveably relative to the developing-agent regulating portion;
• and
• a pressurizing member configured to pressurize the developing-agent bearing member toward the developing-agent regulating portion, wherein a contact portion of the developing-agent regulating portion with the developing-agent bearing member is fixed to the developing container without forming a gap from the developing container on a downstream side in a pressurizing direction of the pressurizing member.
