Abstract
An image forming apparatus includes a developer bearing body and first and second supplying members. An image bearing body and the first and second supplying members are disposed around the developer bearing body in this order. The developer bearing member rotates, and supplies a developer material to the image bearing body. The first and second supplying members rotate in contact with the developer bearing body and supply the developer material to the developer bearing body. The image bearing body is upstream of the second supplying member with respect to rotation of the developer bearing body, and the second supplying member is upstream of the first supplying member. The ratio of the circumferential speed of the first supplying member to that of the developer bearing body is larger than that of the circumferential speed of the second supplying member to circumferential speed of the developer bearing body.
