Abstract:
1. An image forming apparatus having a photosensitive body that forms an electrostatic latent image, and forming an image, the apparatus comprising: a developing section that effects development on the photosensitive body with the formed electrostatic latent image by using a developer; a first replenishment section that replenishes fresh developer to the developing section; a second replenishment section that replenishes recovered developer to the developing section; a first detection section that detects a state of the developer in the developing section; a second detection section that detects an environmental state near the developing section; and a control section that effects control to replenish fresh toner from the first replenishment section and recovered developer to the developing section from the second replenishment section in accordance with a detection result of the firs detection section and a detection result of the second detection section for a predetermined time period, when forcible replenishment of fresh developer to the developing section from the first replenishment section is completed, wherein the control section effects control to replenish only fresh developer to the developing section from the first replenishment section in accordance with a detection result of the first detection section for a predetermined time period, when humidity detected as the environmental state by the second detection section has exceeded a predetermined value.
