An image forming apparatus includes a first image carrying member for carrying a first toner image; a second image carrying member for carrying a second toner image in a maximum amount, of the second toner image carried on the second image carrying member, larger than a maximum amount of the first image carried on the first image carrying member; a first transfer member for electrostatically transferring the first toner image onto a transfer medium in a first transfer nip formed by bringing the transfer medium into contact with the first image carrying member; and a second transfer member for electrostatically transferring the second toner image onto the transfer medium in a second transfer nip formed by bringing the transfer medium into contact with the second carrying member so that a length of the second transfer nip with respect to a movement direction of the second transfer member is longer than a length of the first transfer nip with respect to the movement direction.
