摘要： In adjustment control of a developing device, the number of printed sheets and the toner consumption amount per sheet are calculated. If the accumulated toner consumption amount is smaller than a predetermined amount when a predetermined number of sheets are printed, the developing device is caused to supply a developer in a predetermined amount corresponding to the difference, thereby performing development adjustment of the developing device.

摘要： Provided are an image forming apparatus and method of controlling same in which when toner replenishment from a toner accommodating unit has been performed satisfactorily, a no-toner indication can be cancelled without taking more time than necessary, and in which the status of the toner accommodating unit can be reported to the user earlier even if a toner accommodating unit that has no toner or that has malfunctioned has been installed. Whether a toner accommodating unit (5) has toner is determined based upon a detection signal from a toner density sensor (46) that detects the toner density of a developer in a developing unit (4). If it is determined that there is no toner in the toner accommodating unit (5) and the toner accommodating unit (5) is replaced, this is detected and a toner density restoration sequence for restoring the density of toner in the developing unit (4) is executed. The toner density restoration sequence is controlled based upon a predetermined target value relating to toner density restoration and a toner density restoration decision value (V1) that is different from said predetermined target value.

Also, by the density of the developer in a developing container becoming smaller than a predetermined limit value, a state in which a developing device is not being replenished with the toner from the toner replenishing device is judged. The limit value has a plurality of standards, and a value is selected and used in conformity with the remaining amount of toner in the toner container.

摘要： An image forming apparatus includes a photosensitive drum, a charging roller, a transfer roller, and a toner charging brush, wherein the toner charging brush reciprocates in a longitudinal direction of the photosensitive drum. In the image forming apparatus, when a number of rotations per a unit time of the image bearing member is assumed to be “a” and a number of times of reciprocation per unit time of the toner charging brush is assumed to be “b” assuming that R=b/a, R is set to be in a range of 1/25≦R≦3. However, R=m/n (m and n are integers of 5 or less) is excluded. Consequently, generation of a periodic attachment pattern appearing on the photosensitive drum is eliminated.
