An image developing apparatus includes a latent image carrying member and a developer carrying member. The developer carrying member carries developer which forms a magnetic brush on a surface thereof and causes the magnetic brush to brush a surface of the latent image carrying member in the developing region so that the latent image on the latent image carrying member is visualized. In the apparatus, a developing nip is formed relatively small so that a time period in which a toner of the magnetic brush moves to the developer carrying member back from the latent image carrying member is reduced and a density of the magnetic brush is increased. A developing magnetic pole of the developer carrying member has specific half-angle and attenuation rate values.
