PHOTOSENSITIVE MEMBER UNIT AND DEVELOPMENT UNIT - A simplified explanation of the abstract

This abstract first appeared for US patent application 18464885 titled 'PHOTOSENSITIVE MEMBER UNIT AND DEVELOPMENT UNIT

Simplified Explanation

The abstract describes a photosensitive member unit that includes a photosensitive member, a transfer roller, and a development unit. The unit also includes three helical gears - a first gear and a second gear at one end of the photosensitive member, and a third gear at one end of the transfer roller. The helical teeth of the first gear are inclined in the opposite direction to the helical teeth of the second gear, while the helical teeth of the first gear match the direction of the helical teeth of the third gear.

  • The photosensitive member unit includes a photosensitive member, a transfer roller, and a development unit.
  • The unit also includes three helical gears - a first gear, a second gear, and a third gear.
  • The first gear and the second gear are located at one end of the photosensitive member, while the third gear is located at one end of the transfer roller.
  • The helical teeth of the first gear are inclined in the opposite direction to the helical teeth of the second gear.
  • The helical teeth of the first gear match the direction of the helical teeth of the third gear.

Potential applications of this technology:

  • This technology can be used in photocopiers, printers, and other imaging devices that utilize photosensitive members.
  • It can improve the efficiency and reliability of the transfer process in these devices.

Problems solved by this technology:

  • The helical gears ensure a smooth and efficient transfer of toner from the development roller to the photosensitive member.
  • The opposite inclination of the helical teeth of the first and second gears helps in maintaining a consistent transfer process.

Benefits of this technology:

  • The use of helical gears improves the overall performance and durability of the photosensitive member unit.
  • The consistent transfer process ensures high-quality prints and copies.
  • The simplified design of the unit reduces the complexity of the manufacturing process.


Original Abstract Submitted

A photosensitive member unit includes a photosensitive member, a transfer roller, a mounting portion capable of mounting a development unit including a development roller, a first gear and a second gear each provided at one end of the photosensitive member in an axial direction of the photosensitive member, and a third gear provided at one end of the transfer roller in an axial direction of the photosensitive member and configured to engage with the second gear. The first gear, the second gear, and the third gear are helical gears. A direction in which helical teeth of the first gear are inclined is opposite to a direction in which helical teeth of the second gear are inclined, and the direction in which the helical teeth of the first gear are inclined matches a direction in which helical teeth of the third gear are inclined.
