Image forming apparatus and transfer unit

The invention provides an image forming apparatus and a transfer unit. The image forming apparatus includes: a photoreceptor; a charging member that charges the surface of the photoreceptor; an electrostatic image forming member that forms an electrostatic image on the surface of the charged photoreceptor; a developing member that accommodates a developer containing a toner and forms a toner image by developing an electrostatic image formed on the surface of the photoreceptor using the developer; a transfer member having an endless belt and transferring the toner image onto a recording medium; and a cleaning member having a cleaning blade in contact with the surface of the endless belt and cleaning the surface of the endless belt with the cleaning blade, the coefficient of dynamic friction [mu] between the endless belt and the cleaning blade being 0.10-0.25, the endless belt has an outer peripheral surface on which an uncharged toner is scattered by wind force at a wind pressure of 23 kPa or less at a tempera
