The present invention provides a developing apparatus that can effectively prevent generation of a ghost due to poor detachment of a developer after development, and generation of unevenness in density between a left part and a right part of an image region due to lack of an amount of the developer transported. The developing apparatus satisfies the relationship r+R≦d≦3r+R where r denotes a rotational radius of a second developer transporting screw, R denotes a rotational radius of a development roller, and d denotes a center distance between the second developer transporting screw and the development roller. The developing apparatus also satisfies the relationship M0≧(mg0×v×l)/0.02 where mg0 (g/mm2) denotes an amount of a toner per unit area that is supplied from the development roller to an electrostatic latent image having 100% image coverage which is formed on a photosensitive drum, v (mm/s) denotes a rotational peripheral velocity of the photosensitive drum, l (mm) denotes a maximum printing width on the photosensitive drum, and M0 (g/s) denotes an amount of the developer transported per unit time by the second developer transporting screw in a second developer transport direction.

A developing apparatus has a toner reservoir for holding a non-magnetic toner, a toner supply roller including a supply surface for receiving the toner from the toner reservoir and electrifying the toner thereon, an electrostatic latent image carrier including a curved or flat latent image surface on which a latent image formed by an electrostatic voltage distribution thereon is developed by the toner transferred from the supply surface, and a toner seal surface arranged adjacent to the toner supply roller to contact a remaining part of the toner on the supply surface after the latent image development so that the remaining part of the toner is taken into the toner reservoir. The respective frictional coefficients between the toner seal surface and the toner and between the toner particles are selected to prevent a disturbance of toner condition between the toner and the toner seal surface.
