Abstract:
An electrophotographic imaging unit includes a photoconductor housing, a developer housing, and a support. The photoconductor housing is configured to rotatably support a photoconductor drum. The developer housing is configured to accommodate developer and a developer roller. The support is configured to rotatably support the developer roller at opposite ends thereof. The photoconductor housing and the developer housing are hinged together at one side, and movable relative to each other at another side to open and close the imaging unit to sandwiched the support between the photoconductor housing and the developer housing when the imaging unit is closed.
