IMAGE FORMING APPARATUS

摘要

An image forming apparatus includes process units arranged in a predetermined direction to form a process-unit row, each having a photosensitive body and a developer container; a casing accommodating the process units and having a cover opening and closing an opening formed at one side in the predetermined direction, and an exposure member exposing the photosensitive body, and having a laser source, a deflector, and an optical element, and the exposure member is arranged facing the developer container of each process unit in a direction orthogonal to the predetermined direction. The process units are detachable from the casing, through the opening of the casing, and the developer container of one process unit arranged at one end of the process-unit row has a protruding portion protruding toward the exposure member to overlap with the exposure member in the orthogonal direction.

主权项

1. An image forming apparatus comprising:
a casing defining a first opening and a second opening; a first cover rotatable between a first opened position to expose the first opening and a first closed position to cover the first opening; a second cover rotatable between a second opened position to expose the second opening and a second closed position to cover the second opening; a process unit comprising:
a photosensitive body;a developing unit comprising a developing roller; anda toner cartridge attachable to and detachable from the developing unit for accommodating a developer, wherein the first cover is sized and positioned relative to the toner cartridge to rotate to the first opened position to permit removal of the toner cartridge that is detached from the developing unit while the second cover is maintained in the second closed position, and wherein the first cover and the second cover are sized and positioned relative to the developing unit and the photosensitive body to rotate respectively to the first opened position and the second opened position to permit removal of the developing unit and the photosensitive body integrally.
