Abstract
An easy to install and remove developing unit for an electrophotographic machine is disclosed. The developing unit contains a spring loaded handle that works in cooperation with the top cover or lid of the electrophotographic device. When the lid is opened, the spring loaded handle pops up, allowing the user to grab the handle and pull the developing unit out of the electrophotographic machine. When the lid is closed onto the handle, the cover works against the spring bias and compresses the handle into a small, compact space that fits within the electrophotographic machine. The result is a compact and efficient developing unit that allows the user to easily remove and install the developing unit into and out of the electrophotographic device.
