After performing an image forming operation, a controller controls driving of the image bearing member and the developer carrying member to perform a rotation operation for rotating the image bearing member with rotation of the developer carrying member stopped in a state where an amount of carried developer in the developing portion during the rotation operation is smaller than the amount of carried developer in the developing portion during the image forming operation.
