DEVELOPER STORAGE DEVICE AND IMAGE FORMING APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240094660 titled 'DEVELOPER STORAGE DEVICE AND IMAGE FORMING APPARATUS

Simplified Explanation

The patent application describes a developer storage device that includes a frame with an internal space, an inlet, a partition portion dividing the internal space into two chambers, a communication port in the partition portion, a conveyance portion for moving the developer within the device, and a detection unit to monitor the amount of developer in the first chamber. When the developer level in the first chamber is low, the conveyance portion moves the developer to the far side of the chamber. When the level reaches a predetermined value, the conveyance portion transfers the developer to the second chamber.

  • Frame with internal space, inlet, partition portion, communication port, conveyance portion, and detection unit
  • Partition portion divides internal space into first and second chambers
  • Communication port allows communication between chambers
  • Conveyance portion moves developer within the device
  • Detection unit monitors developer amount in the first chamber
  • Developer is moved to the far side of the first chamber when low
  • Developer is transferred to the second chamber when reaching a predetermined value

Potential Applications

The technology can be applied in:

  • Printer cartridges
  • Toner storage devices
  • Powder dispensing systems

Problems Solved

The device addresses issues such as:

  • Ensuring consistent developer supply
  • Preventing developer wastage

The durability and longevity of the conveyance portion are not discussed in the patent application.


Original Abstract Submitted

a developer storage device that stores developer includes a frame having an internal space and an inlet, a partition portion for partitioning the internal space into first and second chambers, the partition portion including a communication port through which the first and second chamber communicate, a conveyance portion arranged in the internal space and configured to convey the developer, and a detection unit detecting an amount of the developer stored in the first chamber. when the amount of the developer in the first chamber is less than a predetermined value, the developer is conveyed to a far side portion of the first chamber by the conveyance portion. when the detection unit detects that the amount of the developer in the first chamber reaches the predetermined value or more, the conveyance portion conveys the developer to the second chamber.
