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.

Claim (Index 11):
An image forming apparatus comprising:\n a first apparatus body with a first insertion slot portion; a first drum cartridge which is functionally compatible with the first apparatus body, which comprises a photosensitive drum for forming an image, and with which a first cover member is removably attached before the first drum cartridge is mounted to the first apparatus body, the first drum cartridge being capable of inserting into the first apparatus body in an insert direction and of being pulled out of the first apparatus body in a pull-out direction opposite to the insert direction, the first cover member being configured to shade the photosensitive drum; a first guide portion configured to guide the first drum cartridge in a case where the first drum cartridge with the first cover member is inserted into the first apparatus body from the first insertion slot portion, the first guide portion being compatible in shape with the first drum cartridge and a second drum cartridge functionally different from the first drum cartridge; a lock unit configured to lock the 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 the first insertion slot portion by being guided by the first guide portion, and to unlock the first cover member from the first apparatus body if the first drum cartridge is inserted by a second distance which is longer than the first distance by being guided by the first guide portion from the first insertion slot portion; a first portion provided in the first guide portion; and a second portion provided outside of the first drum cartridge, wherein the first and second portions are disposed such that an end face in the pull-out direction of the first portion matches with an end face in the insert direction of the second portion when viewed in one of directions orthogonal to the insert direction and such that the first and second portions do not overlap when viewed in the insert direction in a case where the first drum cartridge is inserted by a third distance which is shorter than the first distance from the first insertion slot portion, wherein the second portion is disposed such that an end face in the pull-out direction of a third portion provided in a second guide portion matches with an end face in the insert direction of the second portion when viewed in one of directions orthogonal to the insert direction and such that the third portion overlaps with the second portion when viewed in the insert direction in a case where the first drum cartridge is inserted into a second apparatus body functionally different from the first apparatus body by the third distance from a second insertion slot portion of the second apparatus body, and wherein the first portion is disposed such that an end face in the pull-out direction of the first portion matches with an end face in the insert direction of a fourth portion provided outside of the second drum cartridge and that permits a second drum cartridge from being inserted into the second apparatus body without butting against the third portion in a case where the second drum cartridge is inserted into the second apparatus body when viewed in one of directions orthogonal to the insert direction and such that the first portion overlaps with the fourth portion when viewed in the insert direction in a case where the second drum cartridge functionally different from the first drum cartridge is inserted by the third distance from the first insertion slot portion.
