An image forming apparatus includes a rotatable brush in contact with an image bearing member at a position downstream of transfer means and upstream of charging means in a rotational direction of the image bearing member. The rotational brush is configured to supply electrical charge to residual toner that remains on the image bearing member. The image forming apparatus executes a mode for removing toner particles attached to the brush by setting a peripheral speed of the brush to be lower than that of the image bearing member during an image forming time period and setting the peripheral speed of the brush to be higher than that of the image bearing member during at least part of a non-image forming time period.
