Abstract
An image forming apparatus includes an image-bearing member bearing a toner image, a transfer unit transferring the toner image on the image-bearing member to a printing medium, a cleaning member rubbing against the image-bearing member and scraping away transfer residual toner from the image-bearing member, and a lubricant applying unit applying a lubricant to the image-bearing member. The apparatus further includes a driving unit driving the lubricant applying unit and a controller controlling the driving unit such that when a period required for an area corresponding to an interval between printing media to pass through a transfer position is longer than or equal to a predetermined set period during image formation, the amount of lubricant applied by the lubricant applying unit is at least lower than that in a case where the period required is shorter than the predetermined set period.
