FIELD: physics.
SUBSTANCE: present invention relates to a method of removing a connecting element and a unit of an electrophotographic light-sensitive drum, used for a process cartridge installed with possibility of removal into the main assembly of an electrophotographic image forming device. Disclosed electrophotographic photosensitive drum unit comprises: (a) cylinder having light-sensitive layer on its outer periphery, (b) a drum flange provided at one end of said cylinder, (c) a coupling member engaged with said drum flange such that the axis of said connecting member is inclined relative to the axis of said drum flange, and (d) a control portion provided on said drum flange so as to prevent disengagement of said connecting member with said drum flange, wherein at least one element of said connecting element and said control part is configured to be deformed to allow coupling of said connecting element with said drum flange or disengage them.
EFFECT: technical result achieved from the implementation of the declared group of inventions is the development of an easily feasible method of removing a connector, as well as in development of electrophotographic photosensitive drum unit, in which removal of connecting element is easy to implement, and in development of electrophotographic photosensitive drum unit, in which installation of connecting element is easy to implement.
