An image forming apparatus includes first and second image forming portions provided with first and second image bearing members, respectively. A controller controls a first operation in which the image to be transferred to the recording material is formed only in the first image forming portion, a second operation in which the image to be transferred is formed in the first and second image forming portions, and a supplying operation in which a lubricant is attached to the second image bearing member and supplied to a contacting portion of the second image bearing member. In a case that a stopping time exceeds a predetermined threshold when a start instruction of the first operation is input in a stopping state of the first and second image bearing members, the controller controls to execute the supplying operation during a time from when a current start instruction of the first operation is input until a next start instruction of the first or second operation is input.
