CARTRIDGE, PROCESS CARTRIDGE AND ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18388253 titled 'CARTRIDGE, PROCESS CARTRIDGE AND ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS

Simplified Explanation

The abstract describes a cartridge for an electrophotographic image forming apparatus that can be attached to a main assembly. The cartridge includes a developing roller, drive transmission members, and a coupling disconnection member to disconnect the transmission members when necessary.

  • The cartridge includes a rotatable developing roller for developing a latent image on a photosensitive member.
  • It has a first drive transmission member to receive rotational force from the main assembly.
  • A second drive transmission member couples with the first member to transmit the rotational force to the developing roller.
  • A coupling disconnection member can separate the transmission members by receiving force from the main assembly and urging them apart.

Original Abstract Submitted

A cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus, the cartridge includes (i) a rotatable developing roller for developing a latent image formed on a photosensitive member; (ii) a first drive transmission member capable of receiving a rotational force originated by the main assembly; (iii) a second drive transmission member capable of coupling with the first drive transmission member and capable of transmitting the rotational force received by the first drive transmission member to the developing roller; and (iv) a coupling disconnection member including a force receiving portion capable of receiving the force originated by the main assembly, and an urging portion capable of urging at least one of the first drive transmission member and the second drive transmission member by the force received by the force receiving portion to separate one of the first drive transmission member and the second drive transmission member from the other, thereby disconnecting the coupling.
