An image forming apparatus includes: a photosensitive drum; a toner cartridge; and a developing unit that forms a toner image by visualizing a latent image formed on the photosensitive drum. The developing unit includes a feed opening through which toner is supplied from the toner cartridge, and a paddle that agitates toner supplied through the feed opening and feeds the toner in a direction of the photosensitive drum. The feed opening has an opening length shorter than a length in a direction of a rotary axis of the paddle, and the paddle includes a toner guide that diffuses the toner in the direction of the rotary axis of the paddle.
