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.

Muffling member for image forming apparatus

A support member is supported in a cylinder included in an image carrier and includes a separation-space-defining portion that is arranged at a certain position in a circumferential direction and extends in an axial direction of the cylinder so that the support member has an arc shape; and a groove-defining portion having a groove depth that changes along the axial direction. A bottom plate of the groove-defining portion is elastically deformed so that the support member presses an inner peripheral surface of the cylinder at least at both ends in the axial direction and is thereby supported in the cylinder.

Support member, image carrier, and image forming apparatus

A support member supported in a cylinder includes six or more contact portions that are in contact with an inner peripheral surface of the cylinder. The support member is arc-shaped and has a gap extending in an axial direction of the cylinder. When the support member is viewed in the axial direction, a groove is formed in the support member such that the groove and the gap are on opposite sides of a center of the cylinder, and the contact portions are symmetrical with respect to a straight line that passes through the centers of the gap and the cylinder. Of the contact portions on one side of the straight line, the farthest contact portions are separated from each other by approximately 90 degrees or more, and the adjacent contact portions are separated from each other by approximately 20 degrees or more in the circumferential direction.

A support member supported in a cylinder included in an image carrier includes a separation-space-defining portion that is arranged at a certain position in a circumferential direction and extends in an axial direction of the cylinder so that the support member has an arc shape; and a groove-defining portion that extends in the axial direction. An outer diameter of the support member in a central region in the axial direction is smaller than an outer diameter of the support member at both ends in the axial direction. In a state in which the support member is supported in the cylinder, the groove-defining portion is elastically deformed such that elastic restoring force generated in the central region is greater than elastic restoring force generated at the ends.

It is a sealing member that seals a gap between one member and the other member, including: a mounting section that has a portion coming into contact with the other member; and an extension section that extends from a side of the mounting section to a side of the one member and is configured to approach the mounting section while coming into contact with the one member by receiving a force from the one member; and a recess that is provided between the mounting section and the extension section and is formed from a part of the mounting section to a part of the extension section, and is recessed from a surface of the mounting section on the side of the one member and a surface of the extension section on a side of the other member.

When an L*a*b* value of a certain color is outside a target color gamut to be converted, it is judged whether the L*a*b* value is located within the range of the color gamut set under a predetermined condition. This set range is a range in which the accuracy is degraded if colors are converted using only a first method, for example, a range in the neighborhood of the color gamut. If a color to be converted is located within the range, colors are converted using a second method. If the L*a*b* value of the color to be converted is outside of the set range, it is converted using the first method until the conversion result is contained within the range Then, the occurrence of both a problem which the first conversion method has for colors in the neighborhood of the color gamut when colors are converted and a problem which the second method has in the conversion of a color far from the color gamut can be suppressed.

Data files in a storage device are ranked in the ascending order of importance. When the storage capacity of the storage device is insufficient for the addition of a new file, the files are deleted automatically in the order of importance beginning with the least important file. Thus, a storage space for the new file is reserved.
