CARTRIDGE INCLUDING PHOTOSENSITIVE DRUM AND DEVELOPING ROLLER THAT CAN BE EASILY SEPARATED - A simplified explanation of the abstract

This abstract first appeared for US patent application 18461819 titled 'CARTRIDGE INCLUDING PHOTOSENSITIVE DRUM AND DEVELOPING ROLLER THAT CAN BE EASILY SEPARATED

Simplified Explanation

The patent application describes a cartridge design for a printing device. The cartridge consists of two units: a first unit with an image bearing member and a second unit with a developer bearing member.

  • The first unit can be removed from the main body of the printer and has a specific posture for removal.
  • The second unit can move between two positions: one where the developer bearing member is in contact with the image bearing member, and another where they are separated.
  • When the first unit is in the removal posture, the second unit is in the second position.
  • In the second position, the movement of the second unit in the direction of separating the developer bearing member from the image bearing member is restricted.

Potential applications of this technology:

  • This cartridge design can be used in various types of printing devices, such as laser printers, inkjet printers, or photocopiers.
  • It can be implemented in both home and office printers, providing a more efficient and user-friendly cartridge replacement process.

Problems solved by this technology:

  • The design ensures that the developer bearing member and the image bearing member are properly aligned when the cartridge is inserted into the printer.
  • It prevents accidental separation of the developer bearing member from the image bearing member during cartridge removal, reducing the risk of damage or contamination.

Benefits of this technology:

  • The cartridge design simplifies the replacement process, making it easier for users to change cartridges without causing any damage.
  • It ensures consistent and accurate printing results by maintaining the proper alignment between the developer bearing member and the image bearing member.
  • The restricted movement of the second unit prevents accidental separation, reducing the risk of contamination and maintaining the quality of prints.


Original Abstract Submitted

A cartridge including: a first unit including an image bearing member and a first portion, and configured to take a removal posture when the cartridge is to be removed from a main body; a second unit including a developer bearing member and a second portion, the second unit being movable between a first position where the developer bearing member is in contact with the image bearing member and a second position where the developer bearing member is separated from the image bearing member and where the second portion is in contact with the first portion, wherein when the first unit takes the removal posture, the second unit is located at the second position, and when the second unit is located at the second position, movement of the second unit in a direction, in which the developer bearing member is separated from the image bearing member, is restricted.
