Abstract:
In an image forming device including a volume supply type developing device, generation of an aggregate of a developer on a back surface of a layer thickness regulating member is suppressed, while occurrence of an image failure caused by the aggregate is suppressed. An image forming device includes: a photosensitive drum; a developing device including a developing roller; a toner container including a toner sensor; and a control portion. According to an increase or decrease of a retention part formed in a first transport path, a toner flows into the developing device from the toner container. The control portion causes the developing roller to reversely rotate at predetermined timing when the toner sensor senses that a residual amount of a toner in the toner container falls below a predetermined threshold value.

Claim (Index 7):
The image forming device according to  claim 1 , wherein\n when causing the developing roller to rotate in the second rotation direction, the drive control portion causes the first transport member and the second transport member to rotate in the same rotation directions as the rotation directions of the first transport member and the second transport member, respectively, when the developing roller is rotated in the first rotation direction.
