Abstract:
An image forming method, comprising the steps of:magnetically adsorbing a magnetized developer onto a developer carrier by the action of a magnetic field generated by a magnetic field generating means to form a magnetic lobe;regulating the amount of said developer in said magnetic lobe in accompaniment with rotation of said 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 said magnetic field normal to said developer carrier becomes zero, to a position of a normal magnetic flux density peak, at which said component of said magnetic field normal to said developer carrier exhibits a maximum value, in a direction in which said developer carrier is rotated; anddeveloping a latent image on an image carrier using said magnetic lobe having a regulated amount of said developer,wherein said magnetic field is generated such that a position of a tangential magnetic flux density peak, at which a component of said magnetic field tangential to said developer carrier exhibits said maximum value, immediately upstream of said developer regulating member in the direction in which said developer carrier is rotated, is positioned upstream of said position of the normal magnetic flux density inflection point in the direction in which said developer carrier is rotated.
