    Abstract: An image forming apparatus includes a developer container having a movable wall therein, a determination unit, a movable wall driving unit, and a movable wall driving controller. The determination unit outputs first determination information when a number of outputs of a signal indicating that a detection sensor has detected a developer is less than a threshold value, and outputs second determination information when the number of outputs thereof is equal to or greater than the threshold value. The movable wall driving unit includes a first driving motor for moving the movable wall and a first driving circuit for controlling driving thereof. The movable wall driving controller includes a signal controller. The signal controller transmits a drive permission signal for the first driving motor when the first determination information is output, and transmits a drive non-permission signal for the first driving motor when the second determination information is output.

  • Patent number: 10133211
    Abstract: A shutter has two engagement portions projecting from a shielding portion, and extending in an attachment direction of the shutter. A lock portion is formed elastically deformably, and a lock claw portion is provided on a tip portion of each lock portion. The lock claw portion is projected toward an outer side in a width direction intersecting an attachment direction of the shutter. Two different inclined surfaces, a second inclined surface and a first inclined surface, are formed on a tip side of the lock claw portion. According to this arrangement, it becomes possible to realize both weakened sliding resistance between the second inclined surface and the attachment contact portion by minimizing an inclination angle of the second inclined surface, and increased sliding resistance between the first inclined surface and a return contact portion by maximizing the inclination angle of the first inclined surface. Thereby, both shutter attachment and return of the shutter to the initial position can be realized.
