1. A developing device comprising:
- a storage container that stores a developer;
a rotating body that supplies the developer to an image holding member in a supply region by being rotated with holding the developer;
an inflow portion that is provided with an inflow port placed on a downstream side of the supply region in a rotation direction of the rotating body, and flows air into the storage container; and
an outflow portion that is provided with an outflow port and emits air in the storage container from the outflow port,wherein the outflow port and the inflow port are placed to be adjacent to each other.

13. A developing device comprising:
-
a storage container that stores a developer; a rotating body that supplies the developer to an image holding member by being rotated with holding the developer; and a flow path that communicates a space inside the storage container with a space outside the storage container, wherein in the flow path, a pressure at an outflow port from which air is emitted is lower than a pressure at an inlet port from which air flows in, and the pressure at the outflow port is equal to a pressure outside the flow path.

14. A developing device comprising:
-
a storage container that stores a developer; a rotating body that supplies the developer to an image holding member; and a divider that divides a space between the rotating body and an inner wall of the storage container into an inflow portion and an outflow portion, wherein the inflow portion and the outflow portion communicate an inside of the storage container with an outside of the storage container, wherein the inflow portion is disposed adjacent to the rotating body and the outflow portion is adjacent to an inner wall of the storage container, and wherein a first distance between the divider and the inner wall of the storage container is different from a second distance between the divider and the rotating body at an outer end portion of the divider which is disposed at a side where the inflow portion and the outflow portion communicate with the outside of the storage container. - View Dependent Claims (15, 16, 17)

18. A developing device comprising:
-
a storage container that stores a developer; a rotating body that supplies the developer to an image holding member; and a divider that divides a space between the rotating body and an inner wall of the storage container into an inflow portion and an outflow portion, wherein the inflow portion and the outflow portion communicate an inside of the storage container with an outside of the storage container, wherein the inflow portion is disposed adjacent to the rotating body and the outflow portion is adjacent to an inner wall of the storage container, wherein a first distance between the divider and the inner wall of the storage container at an outer end portion of the divider is different from a second distance between the divider and the inner wall of the storage container at an inner end portion of the divider, wherein the outer end portion is disposed at a side where the inflow portion communicates with the outside of the storage container, and wherein the inner end portion is disposed at a side where the inflow portion communicates with the inside of the storage container. - View Dependent Claims (19)
