摘要：A developing agent carrying member including magnets is disposed facing an image carrying member, a two-component developing agent containing toner and magnetic carrier is carried in a form of a layer on a surface of the developing agent carrying member, speed difference is generated between the developing agent carrying member and the magnets so as to cause a magnetic brush to flow while forming the magnetic brush on a developing agent layer at least in a facing region where the developing agent carrying member and the image carrying member face one another, and free toner separated from magnetic carrier in a flow of the magnetic brush adheres onto a latent image formed on the image carrying member, whereby developing is performed. A line-shaped latent image is developed with the toner starting from a middle portion thereof in a width direction of the line-shaped latent image.
