Image forming apparatus and transfer unit

An image forming apparatus includes a photoconductor, a charging section that charges a surface of the photoconductor, an electrostatic charge image forming section that forms an electrostatic charge image on the charged surface of the photoconductor, a developing section that accommodates a developer containing a toner and develops the electrostatic charge image formed on the surface of the photoconductor by using the developer to form a toner image, a transfer section that includes an endless belt and transfers the toner image to a recording medium; and a cleaning section that includes a cleaning blade that comes into contact with a surface of the endless belt and performs cleaning of the surface of the endless belt with the cleaning blade, in which a dynamic friction coefficient μ between the endless belt and the cleaning blade is 0.10 or more and 0.25 or less, and the endless belt has an outer peripheral surface on which an uncharged toner is scattered by a wind force of wind pressure of 23 kPa or smaller at a temperature of 22° C. and relative humidity of 55%.
