Abstract
An image forming apparatus includes an image bearing member for carrying an electrostatic latent image; a developing device, containing a developer including a toner and a carrier, for developing the electrostatic latent image carried on the image bearing member into a toner image with the developer; a supplying device for supplying the toner to the developing device; a first detecting portion for detecting information on a temperature of the developing device; a second detecting portion for detecting information on a temperature of the supplying device; and a correcting portion for correcting, when detection results of the first and second detecting portions are different from each other, an image forming condition with increase of a supply amount of the supplying device.
Claims11
An image forming apparatus comprising:
- an image bearing member for carrying an electrostatic latent image;
- a developing device, containing a developer including a toner and a carrier, for developing the electrostatic latent image carried on said image bearing member into a toner image with the developer;
- a supplying device for supplying the toner to said developing device;
- a first detecting portion for detecting information on a temperature of said developing device;
- a second detecting portion for detecting information on a temperature of said supplying device;
- and
- a correcting portion for correcting, when detection results of said first and second detecting portions are different from each other, an image forming condition with an increase of a supply amount of said supplying device.
An image forming apparatus comprising:
- an image bearing member for carrying an electrostatic latent image;
- a developing device, containing a developer including a toner and a carrier, for developing the electrostatic latent image carried on said image bearing member into a toner image with the developer;
- a supplying device for supplying the toner to said developing device;
- and
- a correcting portion for correcting, when temperatures in said developing device and in said supplying device are different from each other, an image forming condition with an increase of a supply amount of said supplying device on the basis of information correlated with temperatures of said developing device and said supplying device.
