Image forming apparatus featuring a regulating member for regulating a number of layers of a developer carried by a developer carrying member |
摘要 |
An image forming apparatus includes an image bearing member for bearing an electrostatic latent image, and a developing device for developing the electrostatic latent image with a developer and collecting the developer remaining on the image bearing member including a developer carrying member for carrying the developer. The developer carried by the developer carrying member comes into contact with the image bearing member as the developer carrying member moves and a regulating member for regulating a layer thickness of the developer carried by the developer carrying member. The regulating member regulates the layer thickness of the developer carried by the developer carrying member so that there will be three to eight layers, wherein V2/V1>1.54 holds where V1 is a peripheral velocity of said image bearing member and V2 is a peripheral velocity of said developer carrying member.
