Abstract
An image forming apparatus includes an image forming portion configured to form a toner image on an image bearing member; an intermediate transfer member onto which the toner image is transferred from the image bearing member in a primary transfer portion to form an image portion; and a control portion configured to perform control to form a toner image for lubrication in a non-image portion of the intermediate transfer member onto which the toner image for a print image based on image information is not to be formed. In a state in which the non-image portion is to be formed downstream of the image portion in a movement direction of the surface of the intermediate transfer member, the control portion performs control to change a size of a region for forming the toner image for lubrication based on the image information.
