Abstract
A developing device includes a developer bearer, a development casing in which a developer conveyance channel is formed facing the developer bearer through a communicating area, a developer supply member disposed in the developer conveyance channel, a developer regulator disposed facing a lower portion of the developer bearer to adjust an amount of developer carried on the developer bearer, and a sheet member that is removably installed to seal the communicating area and passes through a gap between the developer regulator and the developer bearer and an opening formed in the development casing. A first end of the sheet member is retained downstream from the gap in a direction of rotation of the developer bearer, and the sheet member is fixed to the development casing at a position across the communicating area from the first end with a second end positioned outside the development casing.
