Abstract
A developing device includes a developer bearer opposed to an image bearer, configured to bear developer and rotate in a direction of rotation of the developer bearer, and configured to develop a latent image on the image bearer and a casing opposed to the developer bearer at a position downstream from an opposed position, at which the developer bearer is opposed to the image bearer, in the direction of rotation of the developer bearer. A casing gap between the developer bearer and the casing continuously decreases or increases from a first end of the developing device to a second end of the developing device across a center of the developing device in a longitudinal direction of the developing device.
