Title:
CARTRIDGE AND ELECTROPHOTOGRAPHIC IMAGE FORMING DEVICE
Document Type and Number:
Japanese Patent JP2019040220
Kind Code:
A
Abstract:
To solve problems for example, in a cartridge structure in which, a tiltable coupling member which engages with a rotation force transmission part of an electrophotographic image forming device, is employed, when a detachable direction and a developing/separation direction of the cartridge to the electrophotographic image forming device are different, the coupling member cannot engage the rotation force transmission part of the electrophotographic image forming device.SOLUTION: The cartridge comprises: a coupling lever 55 for performing contacting and retreat with respect to a coupling member 180 in linkage with a detachment operation of a developing cartridge B1; and a coupling spring 56 by which the coupling lever 55 acts energization force to the coupling member 180.SELECTED DRAWING: Figure 1
