Abstract
Official abstract text for this publication.
A muffling member for an image forming apparatus includes a thermoplastic member disposed in a photoconductor drum and having a substantially hollow cylindrical shape. The thermoplastic member has a slit-shaped opening at a certain position in a circumferential direction of the thermoplastic member. The thermoplastic member also has a second opening at least at a certain position along the slit-shaped opening, the second opening having an opening width greater than an opening width of the slit-shaped opening.
First claim
Opening claim text (preview).
What is claimed is: 1 . A muffling member for an image forming apparatus, comprising: a thermoplastic member disposed in a photoconductor drum and having a substantially hollow cylindrical shape, wherein the thermoplastic member has a slit-shaped opening at a certain position in a circumferential direction of the thermoplastic member, and wherein the thermoplastic member also has a second opening at least at a certain position along the slit-shaped opening, the second opening having an opening width greater than an opening width of the slit-shaped opening. 2 . The muffling member according to claim 1 , wherein the second opening is formed at substantially the center of the slit-shaped opening. 3 . The muffling member according to claim 1 , wherein the second opening has a substantially rectangular shape in plan view. 4 . The muffling member according to claim 2 , wherein a hinge portion is provided at least at a position where the hinge portion opposes the slit-shaped opening and the second opening in the circumferential direction. 5 . The muffling member according to claim 3 , wherein a hinge portion is provided at least at a position where the hinge portion opposes the slit-shaped opening and the second opening in the circumferential direction. 6 . The muffling member according to claim 4 , wherein the hinge portion is provided at each of three positions in the circumferential direction. 7 . The muffling member according to claim 5 , wherein the hinge portion is provided at each of three positions in the circumferential direction.
