ABSTRACT:
A developing device includes a photosensitive body (18) on which a latent image formed, and a developing roller (2) that rotates to supply a toner to the photosensitive body (18). Seal members (6a) are provided on both end portions of the developing roller (2). The thickness of each seal member (6a) increases along the rotational direction of the developing roller (2) from the upstream to the downstream, so that the pressure with which the seal member (6a) is pressed against the developing roller (2) increases along the rotational direction of the developing roller (2) from the upstream to the downstream.
