ABSTRACT:
An image forming apparatus is constituted by an image-bearing member for bearing a latent image, and a developing apparatus for developing the latent image. The developing apparatus is constituted by a developer container for containing a developer, a developer-carrying member for carrying and conveying the developer contained in the developer container to a developing zone opposite the image-bearing member, and an elastic blade for regulating the developer carried and conveyed on the developer-carrying member to a prescribed thickness to form a thin developer layer on the developer-carrying member. A developer suitable for use in the above developing apparatus is given by a toner, which comprises a binder resin composition which contains 10-70 wt. % of a THF (tetrahydrofuran)-insoluble content and the remainder of a THF-soluble content including a component with a molecular weight of 10000 or below on a GPC (gel permeation chromatography) chromatogram of the THF-soluble content constituting 10-50 wt. % of the binder resin.
