Document Type and Number:
Japanese Patent JP4482202
Kind Code:
B2
Abstract:
A developing apparatus is provided which includes a hollow cylindrical sleeve which is rotationally driven and a magnetic shaft which is rotationally driven inside the sleeve. The magnetic shaft causes magnetic toner to adhere to a peripheral surface of the sleeve by magnetic force. The magnetic toner adhering to the peripheral surface is supplied to a developing position by rotation of the sleeve and adheres to an electrostatic latent image formed on the surface of a photosensitive body. The center of rotation of the magnetic shaft is deviated from the center of rotation of the sleeve nearer to the photosensitive drum, and frontward along the direction of rotation of the sleeve from a line connecting the center of rotation of the sleeve and the center of rotation of the photosensitive body.
