Image forming apparatus |
摘要 |
An image forming apparatus includes an image bearing member where an electrostatic latent image is formed, a developing device developing the electrostatic latent image at a developing position facing the image bearing member, the developing device including a developer bearing member which rotates while bearing developer containing toner and which supplies the image bearing member with the toner, and a regulating member regulating a layer thickness of the developer born by the developer bearing member. In addition, a vibrating member vibrates the regulating member when the vibrating member is driven, and a control unit performs a mode of vibrating the regulating member while rotating the developer bearing member during a non-image forming period and of transferring from the developer bearing member to the image bearing member the toner passing through the regulating member during vibration of the regulating member. |

1. An image forming apparatus, comprising:
an image bearing member on which an electrostatic latent image is formed; a developing device which develops the electrostatic latent image at a developing position facing the image bearing member, the developing device including a developer bearing member which rotates while bearing developer containing toner and which supplies the image bearing member with the toner; a regulating member which regulates a layer thickness of the developer born by the developer bearing member; and a vibrating member which vibrates the regulating member when the vibrating member is driven; and a control unit that performs a mode of vibrating the regulating member while rotating the developer bearing member during a non-image forming period and of transferring from the developer bearing member to the image bearing member the toner which passes through the regulating member during vibration of the regulating member. |
