Abstract
A development device includes a developer bearer to carry by rotation developer to a development range facing a latent image bearer, and a developer regulator to adjust an amount of developer transported to the development range by the developer bearer. Multiple projections are formed in a surface of the developer bearer, and, in a direction in which the developer bearer rotates, a downstream end of each of the multiple projections is higher than an upstream end of the projection.
