An electrophotographic image forming apparatus is provided including a body including an opening and a first coupler, a photoreceptor cartridge including a second coupler connected to the first coupler, a first gear connected to the second coupler, and a mounting portion, and attached to or detached from the body through the opening; and a development cartridge including a second gear connected to the first gear and attached or detached from the mounting portion through the opening while the photoreceptor cartridge is mounted in the body.

Electrophotographic image forming apparatus

An electrophotographic image forming apparatus is provided including a body including an opening, a photoreceptor cartridge attached to, or detached from, the body through the opening and including a mounting portion, a development cartridge attached to, or detached from, the mounting portion through the opening when the photoreceptor cartridge is mounted in the body, and a cover opening or closing the opening and fixing the development cartridge to the mounting portion by pressurizing the development cartridge while the opening is closed.

A developing unit and an image forming apparatus are disclosed. The developing unit includes an image carrier on which an electrostatic latent image is formed, a developing member to supply a developer to the image carrier, and a first cleaning member having a first cleaning blade to remove a non-transferred developer on the image carrier. The first cleaning blade is configured to be reversible between a counter disposition, which is opposite to a rotation direction of the image carrier while the image carrier is in a printing operation, and a trailing disposition, which corresponds to the rotation direction.
