Abstract
A developing device includes a hardware processor that performs control in which a developer circulation state is switched between a first state and a second state depending on states of the developer in the first and the second regions. The first state is a state in which a developer circulation path is formed in each of the first and the second regions, and the second state is a state in which a single developer circulation path is formed all through the first and the second regions.
Claims27
A developing device comprising:
- a developer bearing member that bears developer;
- a developer housing that stores the developer to be supplied to the developer bearing member, the developer housing including a first region on one side in an axial direction of the developer bearing member and a second region on the other side;
- and
- a hardware processor that performs control in which a developer circulation state is switched between a first state and a second state depending on states of the developer in the first and the second regions, the first state being a state in which a developer circulation path is formed in each of the first and the second regions, the second state being a state in which a single developer circulation path is formed through both of the first and the second regions, wherein both of the first region and the second region face the developer bearing member.
An image forming apparatus comprising:
- a developer bearing member that bears developer;
- a developer housing that stores the developer to be supplied to the developer bearing member, the developer housing including a first region on one side in an axial direction of the developer bearing member and a second region on the other side;
- and
- a hardware processor that performs control in which a developer circulation state is switched between a first state and a second state depending on states of the developer in the first and the second regions, the first state being a state in which a developer circulation path is formed in each of the first and the second regions, the second state being a state in which a single developer circulation path is formed through both of the first and the second regions, wherein both of the first region and the second region face the developer bearing member.
