摘要： A developing device includes a developer carrying member, rotatable while carrying a developer, for supplying developer to an image bearing member, a developer supplying member, which is provided with a foam layer at its surface and is rotatable in contact with the developer carrying member, for supplying the developer to the developer carrying member, and a first gear for transmitting a driving force to the developer supplying member. The first gear is movable to a first position where the driving force is not transmitted to the developer supplying member and to a second position where the driving force is transmitted to the developer supplying member. During initial drive of the developer carrying member, the developer supplying member is rotated by a frictional force generated between the developer supplying member and the developer carrying member, with the first gear to be moved from the first position to the second position.

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： The image forming apparatus includes an image bearing member; a transfer belt used to transfer a toner image from the image bearing member to a transfer material; a transfer unit adapted to form a transfer nip in conjunction with the image bearing member through the transfer belt; and a control part adapted to control a rotation direction of the transfer belt, wherein in a cleaning mode, the control part rotates the transfer belt in a direction opposite to the rotation direction of the transfer belt during image formation at least by an amount equal to or larger than width of the transfer nip in the rotation direction of the transfer belt. This prevents foreign material from being trapped between the transfer belt such as an intermediate transfer belt or transfer material conveyance belt and a sheet member and thereby reduces density irregularities in a longitudinal direction of the belt.
