Abstract
An image forming apparatus includes a plurality of developing portions. Each of the developing portions includes a developer supporting member for supplying developer containing at least a binder resin to an image supporting member that supports a static latent image to develop the static latent image; and a layer regulating member arranged to contact with a surface of the developer supporting member and regulate a layer of developer. The image forming apparatus includes a first developing portion that uses first developer containing a metal oxide in the binder resin, and a second developing portion that uses second developer containing no metal oxide in the binder resin. The layer regulating member of the first developing portion is configured to apply a pressure to the developer supporting member smaller than that of the layer regulating member of the second developing portion applied to the developer supporting member.
