ABSTRACT:
The present invention is intended to provide an image forming apparatus capable of producing high-quality images for a long period of time wherein the consumption of the opposite polarity particles is reduced, and a reduction in the amount of toner charge resulting from carrier deterioration is minimized, even if a great number of images having a low image area ratio were printed. This image forming apparatus is characterized in that the surface of an image carrying member, which is placed face to face with a toner carrying member, and on which an electrostatic latent image to be developed with the toner supported on the toner carrying member is formed, has an contact angle of 95 degrees or more with respect to pure water.
