    Abstract: A volume detector for detecting the volume of powdery material in a container includes a roller having a fin and rotatably provided in the container for generating a periodic wavy motion of the powdery material so as to cause at least a portion of the powdery material to rise above and fall below a predetermined level. A level sensor is provided at the predetermined level in the container for producing high and low level signals, respectively, when at least a portion of the powdery material rises above and falls below the predetermined level. The signal produced from the level sensor is applied to a duty cycle detector for detecting the duty cycle of high level signal, thereby the duty cycle representing the volume of the powdery material.

    Abstract: An apparatus for detecting the level or quantity of a particulate material contained in a vessel by means of an agitating and/or delivering member while agitating the particulate material which needs to be agitated from time to time. The agitating member is arranged in the vessel for rotation about a horizontal axis, the center of gravity of the agitating member deviating from said horizontal axis. A driving and a driven disks disposed in spaced juxtaposed relationship constitute drive means for driving the agitating member. Arranged between the driving and driven disks is coupling means which, while permitting the disks to rotate relative to each other through a predetermined angle, connects the two disks to each other when the disks reach an end of said angle. Thus, when the agitating member is drawing, during its movement, near the upper surface of the particulate material in the vessel, it is disconnected from the drive source due to its eccentricity while the two disks are moving through said angle, and further moves by its own weight till it reaches the upper surface of the particulate material where it temporarily remains stationary. The angular position reached by the driven disk at this time indicates the level or the gravity of the particulate material in the vessel. Detection of the level of particulate material can be readily achieved by observing the angular relationship of the two disks at the time when the agitating member becomes stationary.

    Abstract: A developing device of an image forming apparatus includes a casing, two-component developer accommodated in the casing, and a stirring screw for conveying and stirring the developer in the casing by rotation in a predetermined direction. The image forming apparatus includes a toner concentration sensor that outputs a value indicative of the toner concentration of the developer in the casing. The image forming apparatus determines whether or not the developer in the casing has become uniform, based on the amount of change per unit time of the output value of the toner concentration sensor, acquired after the stirring of the developer in the casing by the stirring screw is started. It is possible to appropriately measure the reference value of the toner concentration.
