Abstract:
A developing apparatus comprising:developing means having a first magnetic pole opposed to an image carrier on which an electrostatic latent image is formed, and a second magnetic pole arranged at a predetermined angle to the first magnetic pole, for supplying the electrostatic latent image with developing agent having toner and carrier, the second magnetic pole of the developing means having a polarity; andcarrier collection means having a third magnetic pole of a polarity opposite to that of the second magnetic pole of the developing means, a fourth magnetic pole of a polarity equal to that of the second magnetic pole of the developing means, and a fifth magnetic pole of a polarity opposite to that of the second magnetic pole of the developing means, for collecting the carrier on the image carrier by the third magnetic pole and for carrying the collected carrier, by the fourth and fifth magnetic poles, the fourth magnetic pole being arranged to be opposed to the second magnetic pole of the developing means in the carrier collection means.
