摘要： An image forming apparatus includes an image holding body, a developing device, a transfer device, a collection device, a container, and a transport member. The image holding body includes a surface on which a latent image is formed. The developing device develops the latent image into a visual image with developer. The transfer device transfers the visual image onto a transfer medium. The collection device collects the developer remaining on the surface of the image holding body after the visual image has been transferred. The container contains new developer supplied to the developing device. The image forming apparatus has a channel that has a first sub-channel and a second sub-channel. The developer flows into the first sub-channel from one of the collection device and the container and the second sub-channel from the other of the collection device and the container.
