    摘要: An image forming apparatus includes a developing device, a detection mode execution unit, and a notice signal generating unit. The developing device supplies a toner bearing member with toner in a container by rotating a toner supply member in a contact manner with the toner bearing member. The detection mode execution unit executes a detection mode in which a predetermined period for changing a toner amount in the foam layer by rotating the toner supply member is provided, a capacitance C1 between the first and second electrode members is detected before the predetermined period, and a capacitance C2 between the first and second electrode members is detected after the predetermined period. The notice signal generating unit generates a low toner amount notice signal in response to an absolute value |C1−C2| of a difference between the capacitances C1 and C2 being smaller than a predetermined threshold.

    摘要: In an image forming apparatus of a rotary type, when a pause is made during continuous image formation, the time taken to restart image formation after the pause is shortened so as to reduce stress on the user. In the image forming apparatus, it is determined beforehand whether the next image formation mode is a color mode or a mono mode, and a developing device to be first used in the next image formation mode is moved to a developing standby position.

    摘要: An image forming apparatus includes a rotary for changing an attitude of a developing device to a first attitude in which developer in a developer accommodating chamber is feedable to a developer feeding member and to a second attitude in which the developer having been located above a nip between the developer feeding member and a developing roller drops from the nip. In the image attitude of the developing device, an electrostatic latent image is developed. In the second attitude of the developing device, detection of a remaining amount of the developer is carried out.
