Abstract
A developing device configured to develop a latent image formed on an image bearing member includes a rotatable developing-agent bearing member configured to bear developing agent, 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 movably 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. 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.
