Abstract:
A development device includes a developing section to visualize a latent image formed on a latent image carrier with developer including toner and carrier. The development device has a developer supply opening and a developer collection opening, a circulation unit to transport the developer collected from the developer collection opening of the developing section to the developer supply opening of the developing section and including a developer container to store the developer collected from the developing section disposed upstream from the development section in a direction in which the developer is circulated, and a developer cooler to cool the developer contained in the developer container.
