増量制御方式。[Scope of Claim for Utility Model Registration] (1) In a toner increase control method in an image forming apparatus that develops a latent image on a latent image carrier into a visible image, a toner increase operation means is provided in the main body of the image forming apparatus; A toner amount increase control method in an image forming apparatus, characterized in that when the amount of toner is increased by operating a toner amount increase operation means, only the components related to the toner dispensing operation in the developing machine other than the developing roll are rotationally driven. . (2) A clutch that is normally held in a connected state is provided between the developing roll and a driving means for driving the developing roll and the component parts, and the amount of toner is increased by operating the toner amount increasing operation means. 2. The toner increase control method for an image forming apparatus according to claim 1, wherein the clutch is disengaged when the clutch is turned off. (3) In a toner increase control method in an image forming apparatus that develops a latent image on a latent image carrier into a visible image, the toner concentration detected by the toner concentration detection means just before the end of the developing machine job (JOB) When the control device determines that the toner concentration is lower than a predetermined concentration, the control device calculates the required toner amount and required dispense time based on the detected toner concentration, and calculates the required toner amount and dispense time during standby until the next job. A toner increase control method in an image forming apparatus characterized by driving a developing machine for a certain amount of time. (4) When the required dispensing time is insufficient due to the normal toner dispensing time in the JOB, the insufficient time is stored in a buffer within the control device, and the time is stored in the buffer during the standby. 4. The toner amount increase control method in an image forming apparatus according to claim 3, wherein the developing device is driven for a period of time during which the toner amount increases. (5) The toner amount increase control system in an image forming apparatus according to claim 3 or 4, wherein the toner concentration detection means is an agricultural rate reading sensor of automatic development control (ADC). (6) The toner amount increase control method in an image forming apparatus according to claim 3 or 4, wherein the toner density detection means is a density reading sensor of an area coverage dispense control (ACDC).
