An image forming method for improving developer recirculation capability within a developer unit includes the steps of magnetically adsorbing a developer having magnetism onto a developer carrier by the action of a magnetic field generated by a magnetic field generating member to form a magnetic lobe, regulating the amount of developer in the magnetic lobe in accompaniment with rotation of the developer carrier about a longitudinal central axis by a developer regulating member disposed in a developer carrier rotating angular region extending from a position of a normal magnetic flux density inflection point, at which a component of the magnetic field normal to the developer carrier becomes zero, to a position of a normal magnetic flux density peak, at which the component of the magnetic field normal to the developer carrier exhibits a maximum value, in a direction in which the developer carrier is rotated, and developing a latent image on an image carrier using the magnetic lobe having a regulated amount of developer, wherein the magnetic field is generated such that a position of a tangential magnetic flux density peak, at which a component of the magnetic field tangential to the developer carrier exhibits a maximum value, immediately upstream of the developer regulating member in the direction in which the developer carrier is rotated, is positioned upstream of the position of the normal magnetic flux density inflection point in the direction in which the developer carrier is rotated.
