Abstract
An image forming apparatus including an image transport member driven to rotate with a latent image formed on a surface thereof, and a toner transport member driven to rotate with toner attached thereto for developing the latent image and in contact with the image transport member to transport the toner to the image transport member. The image forming apparatus further includes a toner layer thickness regulating member disposed in pressure contact with the surface of the toner transport member to regulate the thickness of a layer of toner transported in a state of being attached to the surface of the toner transport member. The amount of charge of the toner on the surface of the toner transport member is regulated in the range of from -16 .mu.C/g to -19 .mu.C/g.
