摘要： A developing device for developing a latent image on an image carrying member includes a container member containing toner; a development roller provided at a development opening of the container member; a first toner conveying member disposed so as to face the development roller, wherein a direction of rotation of said first developer conveying member is opposite to a direction of rotation of said developer carrying member; and a second toner conveying member provided further downstream from the first conveying member as viewed in the direction of rotation of the development roller and having a higher conveying capability than the first toner conveying member. The toner circulation capability around the development roller is very high.

摘要： An image forming apparatus having an image bearing member for carrying an image, a transfer member for urging a recording sheet against the image bearing member and transferring an image onto the recording sheet, a driving means for rotationally driving the image bearing member, and a driving force transmission means for transmitting a driving force from the driving means to the transfer member through the image bearing member. The transfer member is then rotated so that the peripheral speed of a portion of the transfer member which urges the sheet against the image bearing member is higher than the peripheral speed of the image bearing member. The image forming apparatus satisfies the following inequality: R.sub.D W.sub.D
