摘要： An image forming apparatus includes: an image bearing member, a developing device, and a controller configured to execute an operation in a forced consumption mode. The controller includes a difference calculating portion, an integrating portion, and a flag. In a case where the flag is set when a predetermined time is elapsed after the integrated value exceeds the predetermined threshold, the image formation on the predetermined number of the recording materials is effected and then the controller executes the operation in the forced consumption mode, and in a case where the flag is reset when the predetermined time is elapsed after the integrated value exceeds the predetermined threshold, the image formation on the predetermined number of the recording materials is effected and then the controller continues an image forming operation without executing the operation in the forced consumption mode.

摘要： In a method for controlling a development process in an electrographic printer or copier, a mixture of toner and carrier particles is used. For the state of the mixture, a characteristic value D or E is determined from model calculations, an operating ageing rate or a time constant being taken into account. The development process is subjected to open-loop or closed-loop control depending on the characteristic values D and/or E.

摘要： The invention provides a developer supply device, a developer container, a developer and an image forming apparatus such that the developer is discharged stably from the developer container with a stable toner concentration in the developer, without damaging the developer, and in a relatively simple and small-size device having a relatively high degree of freedom as regards layout. The developer supply device comprises a partially or wholly deformable developer container and a pump for suctioning the developer held in the developer container, together with a gas, and for discharging the developer towards a developing unit. The toner comprises an additive formed so as to have a volume average particle size of 50 to 500 nm. The carrier is formed so as to have a weight average particle size of 20 to 60 µm. The developer is formed so that the carrier concentration thereof is 1 to 30wt%.
