Cartridge, attachment and mounting kit
To further develop a drive transmission method from a main assembly of an apparatus toward a cartridge. The cartridge is detachably mountable to a main assembly of an image forming apparatus including a drive output member configured to output a driving force, and a main assembly side pushing member configured to incline the drive output member by pushing the drive output member. The cartridge includes a photosensitive drum and a cartridge side pushing member. The cartridge side pushing member is configured such that an inclination angle of the drive output member is changed by pushing the main assembly side pushing member.
1 . A mountable kit comprising:
an attachment detachably mountable to a main assembly of an image forming apparatus, the attachment including a body and a gear that is rotatable about a rotational axis, with the gear being movable relative to the body of the attachment such that the rotational axis of the gear is movable relative to the body of the attachment; and
a cartridge separate from the attachment, the cartridge being detachably mountable to the main assembly of the image forming apparatus and including a photosensitive drum.
2 . A mountable kit according to claim 1 , wherein the attachment further includes a spring urging the gear.
3 . A mountable kit according to claim 1 , wherein the attachment further includes a lever that is movable relative to the body of the attachment, and
wherein the lever is configured to move the gear such that the rotational axis of the gear moves relative to the body of the attachment with movement of the lever.
4 . A mountable kit according to claim 3 , wherein the attachment further includes a spring urging the gear via the lever.
5 . A mountable kit according to claim 1 , wherein the cartridge further includes a coupling operatively connected to the photosensitive drum.
6 . A mountable kit according to claim 5 , wherein the cartridge further includes a protrusion protruding in an axial direction of the photosensitive drum and is provided on the side same as the side where the coupling is provided in the axial direction, wherein the rotational axis of the gear is movable between a first position and a second position, and
wherein, when viewed along the axial direction, a distance between the rotational axis of the gear and the protrusion when the rotational axis of the gear is in the first position is less than the distance when the rotational axis of the gear is in the second position in a state where the attachment and the cartridge are mounted to the main assembly of the image forming apparatus.
7 . A mountable kit according to claim 5 , wherein the cartridge further includes a protrusion protruding in an axial direction of the photosensitive drum and is provided on a side same as a side where the coupling is provided in the axial direction, and
wherein, in a state where the attachment and the cartridge are mounted to the main assembly of the image forming apparatus and when viewed along the axial direction, the coupling is positioned between the attachment and the protrusion.
8 . A mountable kit according to claim 1 , wherein the cartridge further includes a developing roller configured to develop a latent image on the photosensitive drum.
9 . A mountable kit according to claim 1 , wherein the rotational axis of the gear is movable between a first position and a second position, a distance between the rotational axis of the gear and an axis of the photosensitive drum when the rotational axis of the gear is in the first position being smaller than the distance when the rotational axis of the gear is in the second position in a state where the attachment and the cartridge are mounted to the main assembly of the image forming apparatus.
10 . A mountable kit according to claim 1 , wherein the rotational axis of the gear is movable between a first position and a second position, a distance between the rotational axis of the gear and an axis of the photosensitive drum when the rotational axis of the gear is in the first position being smaller than the distance when the rotational axis of the gear is in the second position in a state where the attachment and the cartridge are mounted to the main assembly of the image forming apparatus.
11 . A mountable kit according to claim 1 , wherein the gear is configured to be engageable with a gear provided at a drive transmission member included in the main assembly of the image forming apparatus.
12 . An image forming apparatus comprising:
a main assembly including an inclinable drive transmission member;
an attachment detachably mountable to the main assembly, the attachment including a body and a gear that is rotatable about a rotational axis, with the gear being movable relative to the body of the attachment such that the rotational axis of the gear is movable relative to the body of the attachment; and
a cartridge separate from the attachment, the cartridge being detachably mountable to the main assembly of the image forming apparatus and including a photosensitive drum,
wherein the drive transmission member includes a gear configured to engage the gear of the attachment.
