An image forming apparatus includes a secondary transfer roller that is supported by a secondary-transfer-unit supporting unit and transfers a toner image onto a recording medium, a lubricant applying brush that comes into contact with the secondary transfer roller and applies a lubricant to the secondary transfer roller, a solid lubricant that is housed in a lubricant-applying-brush housing unit and supplies the lubricant to the lubricant applying brush, and a lubricant holding member that elastically holds the solid lubricant. The lubricant is supplied to the secondary transfer roller according to a material of the lubricant, a pressing amount of the lubricant against the secondary transfer roller, a configuration of the secondary transfer roller, a configuration of the fur brush, and a relation among fur brush circumferential speed, secondary transfer roller circumferential speed, a pressing amount of a blade against the secondary transfer roller, and a blade material.
