A binding apparatus includes: an accumulating unit where a plurality of sheets having an area that serves as a binding margin is to be stacked as a sheet bundle, in which toner is fixed onto all of, or a part of, the area; a pressure unit that sandwiches the binding margin of the sheet bundle stacked on the accumulating unit therebetween and applies a pressure to the binding margin; and a heating unit that heats the toner on the binding margin that is receiving the pressure applied by the pressure unit. The pressure unit is configured to apply the pressure to the binding margin while forming a plurality of grooves and ridges in the binding margin in a direction in which the pressure is applied.

An image reading device, which is included in an image forming apparatus and used to perform a method of reading images, includes an image reading body configured to read one of a recording medium and the recording medium together with a background area adjacent to the recording medium, a moving body disposed facing the image reading body, and a reference body as a reference in shading correction. The moving body is configured to hold the recording medium and the reference body in a direction intersecting a sheet conveying direction of the recording medium such that the recording medium and the reference body contact to and separate from the image reading body.

A planetary gear mechanism includes a plurality of planetary gears, an outer gear, a sun gear, a carrier, and a stick mount. The outer gear meshes with the plurality of planetary gears. The sun gear is coaxially disposed on the same axis as the outer gear and transmits force to the planetary gears. The carrier rotatably supports the plurality of planetary gears and is rotatably and floatingly supported. The carrier includes a hole through which a stick member penetrates in a direction of axis of rotation of the carrier. The stick member penetrates through the hole and is mounted on the stick mount. The stick mount is disposed opposite the carrier. The outer gear and the sun gear are held such that one of the outer gear and the sun gear does not rotate.

A sheet conveying device, which is included in an image forming apparatus, includes a sheet holding roller to move while holding a sheet, a detector to perform a primary detection to detect a sheet position before the sheet holding roller holds the sheet and a secondary detection to detect a sheet position downstream from the sheet position detected by the primary detection, and a controller configured to cause the sheet holding roller to perform a first drive to move the sheet holding roller in at least one direction of a width direction of the sheet and a rotation direction in a sheet conveying surface based on a result of the primary detection and a second drive to move the sheet holding roller opposite to the at least one direction of the first drive, based on a result of the secondary detection.
摘要:
A sheet conveying device, which is included in an image forming apparatus and a post processing device, includes multiple position detectors and a position corrector. The multiple position detectors are aligned along a sheet conveying direction and configured to detect a side end of a sheet. The position corrector is configured to convey the sheet and correct a position of the sheet based on a positional deviation amount of the sheet, obtained by a detection result of the multiple position detectors. The positional deviation amount of the sheet is obtained by an extreme downstream position detector in the sheet conveying direction, of the multiple position detectors. A position of a subsequent sheet is corrected based on a sum of the positional deviation amount of the sheet and a positional deviation amount of the subsequent sheet.

A sheet conveying device, which is included in an image forming apparatus and a post processing device, includes a position corrector and either one of a rolling body and a contact resistance reducer. The position corrector is configured to convey a sheet and correct a position of the sheet. The rolling body is disposed at least one of an upstream side and a downstream side of a sheet conveyance passage from the position corrector in a sheet conveying direction and is configured to roll in at least a direction intersecting the sheet conveying direction. The contact resistance reducer is configured to reduce contact resistance generated due to contact of the sheet to a neighboring part when the position of the sheet is corrected by the position corrector.
