摘要： Provided is a developing device capable of, with a simple structure, preventing occurrence of image degradation ascribable to a distribution of an amount of fall in a longitudinal direction due to developer replenishment within a developer container. An upper rim portion of a developer regulating wall for adjusting an amount of a developer falling along a developer transport direction of a developer transport path is inclined so as to become low in height in the developer transport direction of the developer transport path. A width of a surface in the developer transport direction of the developer transport path is enlarged along the developer transport direction of the developer transport path. A wall is formed by the developer transported on the developer transport path, and the developer transported in a longitudinal direction is transported in the longitudinal direction while breaking a wall of the developer itself.

摘要： The present invention provides a development roller disposed in proximity of a photosensitive body which is charged by a charging member and on which an electrostatic latent image is formed, the development roller performing development by transferring toner to the photosensitive body. The development roller includes a toner layer formation area where a toner layer is formed on a surface of a development roller main body portion and a small diameter portion which has a diameter smaller than that of the toner layer formation area and which is located in at least a part of an area where the toner layer is not formed on the surface of the development roller main body portion.
