Abstract:
An image forming apparatus includes an image bearing member; a developing device including a developer container, a feeding member, and a developer carrying member; a toner supplying portion including a feeding screw, and a controller; and a supply rotation number determining portion. The controller controls the driving portion so that the feeding screw is rotated at a first rotational speed when the supply rotation number determining portion determines a number of times of the rotation at a first integer of times of rotation and so that the feeding screw is rotated at a second rotational speed slower than the first rotational speed when the supply rotation number determining portion determines the number of times of the rotation at a second integer of times of rotation smaller than the first integer of times of rotation.

Claim (Index 9):
An image forming apparatus comprising:\n an image bearing member; a developing device including a developer container accommodating a developer containing toner and a carrier, a feeding member configured to feed the developer, and a developer carrying member configured to carry and feed the developer;\n a toner supplying portion including a feeding screw configured to feed the toner to be supplied to said developing device, a driving source configured to rotationally drive said feeding screw, and a controller configured to control drive of said feeding screw, wherein in said toner supplying portion, a first integer of times of rotation of said feeding screw in a predetermined period is a maximum integer and is set in advance, and wherein an amount of the toner to be supplied to said developing device is controlled by an integer of times of rotation of said feeding screw in the predetermined period; and \n a supply rotation number determining portion configured to determine a number of times of rotation of said feeding screw for supplying the toner to said developing device, depending on an image signal, \n wherein said controller effects controls so that the toner is supplied to said developing device by rotating said feeding screw at a first rotational speed when an image with a first roller is continuously formed and so that the toner is supplied to said developing device by rotating said feeding screw at a second rotational speed slower than the first rotational speed when an image with a second image ratio smaller than the first image ratio and smaller than a predetermined value is continuously formed.
