Abstract:
An image forming apparatus includes a first apparatus body, a first drum cartridge, a first guide portion, a lock unit, and a first erroneous insertion blocking portion. The lock unit is configured to lock a first cover member with the first apparatus body if the first drum cartridge with the first cover member is inserted by a first distance from a first insertion slot portion by being guided by the first guide portion. The first erroneous insertion blocking portion is configured to permit the first drum cartridge to be inserted into the first apparatus body and to block a second drum cartridge, functionally different from the first drum cartridge, to be inserted into the first apparatus body in a range exceeding a third distance shorter than a first distance from the first insertion slot portion.
