A detecting apparatus includes: a light emitting element which emits light toward a detection material; a light receiving element which receives reflected light from the detection material; and an apparatus main body having an opening/closing member which opens and closes an opening through which light emitted from the light emitting element and reflected light from the detection material pass through, the apparatus main body being capable of moving between a first position where the apparatus main body comes into contact with the detection material and a second position where the apparatus main body separates from the detection material, and the opening/closing member being configured to open when the apparatus main body moves to the first position and to close when the apparatus main body moves to the second position.

Detecting apparatus and image forming apparatus

The driving force transmission apparatus, in which on at least one of portions of a first rotary member and a second rotary member opposed to each other under a state in which a driving rotary member and a driven rotary member are opposed to each other through a first non-engaging portion, includes a non-contact portion at which the first rotary member and the second rotary member are prevented from being brought into contact with each other is formed, wherein the non-contact portion is configured to cut torque transmitted from a driven member side to the first rotary member side through the second rotary member.

Driving force transmission apparatus and image forming apparatus

An inclined flange roller is located outward of an end portion of a tension roller in the belt width direction. The inclined flange roller includes a flange surface capable of being in contact with the edge portion of a belt in a region in which the belt is wound around the tension roller and a roller surface capable of being in contact with an inner peripheral surface of the belt between the flange surface and an end portion of the tension roller in the belt width direction.

Belt conveyor unit and image forming apparatus

An image forming apparatus including: a sheet feeding portion configured to feed a sheet to a sheet conveying path; an image forming portion configured to form an image on the sheet; a sheet discharging portion configured to discharge the sheet; a sheet re-conveying path configured to guide the sheet on which the image has been formed to the sheet conveying path again; an original feeding portion configured to feed an original; an original feeding path configured to guide the original to the sheet re-conveying path; an image reading portion configured to read an image of the original; an original discharging path configured to guide the original guided along the sheet re-conveying path to an original discharging portion; and an original conveying portion configured to convey the original which has been guided along the original feeding path toward the original discharging path.

Image forming apparatus

An image forming apparatus includes a first conveying path guiding a sheet such that the sheet passes through the image forming portion, a second conveying path guiding the sheet on which the image is formed by the image forming portion to the first conveying path. A document is fed to the second conveying path and the image forming apparatus includes a first drive transmission portion transmitting a drive force to the image forming portion and a second drive transmission portion transmitting the drive force to a document feeding portion, a conveyance portion and a document discharge portion.

Image forming apparatus having multiple paper feeding paths

A rotating member provided on an end of a stretching member is rotatable around a rotating axis inclined with respect to the shaft of the stretching member. In order that, when a belt end winds around the rotating member, the belt end winds around an outer side of an entry position where the belt end enters the rotating member, an outer circumferential surface of the rotating member in an area in contact with an inner circumferential surface of the belt is inclined with respect to a belt contact surface.

Belt conveyance apparatus and image forming apparatus having an endless belt

An image forming apparatus includes a first conveying path which connects between a sheet feed portion and a sheet discharging portion, and on which a image forming portion is arranged. The image forming apparatus further includes a second conveying path configured to guide the sheet on which the image has been formed on one surface thereof by the image forming portion to the first conveying path again, a document conveying path, and a reading portion. The document conveying path includes a document feeding path, a document discharging path, and a common conveying path which serves as at least a part of the second conveying path, and guides the document from a document feed portion to a document discharging portion through the document feeding path, the common conveying path and the document discharging path without causing the document to pass through the image forming position. The reading portion reads a first face and a second face of the document which is fed from the document feed portion.

An image forming apparatus includes a sheet feed portion configured to feed a sheet, an image forming portion configured to form an image on the sheet, a first conveying path configured to guide the sheet fed from the sheet feed portion such that the sheet passes through the image forming portion, a second conveying path configured to guide the sheet on which the image has been formed on one surface thereof by the image forming portion to the first conveying path again, a document feed portion configured to feed a document to the second conveying path, an image reading portion configured to read an image of the document fed by the document feed portion, and a control portion configured to control the sheet feed portion and the document feed portion such that the document and the sheet are conveyed on the second conveying path in a sequence in which the document and the sheet are mixed in a case where an operation of forming images respectively on both surfaces of a plurality of sheets overlaps with an operation of reading images of a plurality of documents.

Reading apparatus

An image forming apparatus has a first conveying path guiding a sheet such that the sheet passes through the image forming portion, a second conveying path guiding the sheet on which the image is formed by the image forming portion to the first conveying path. A document is fed to the second conveying path and the image forming apparatus has a first drive transmission portion transmitting a drive force to the image forming portion and a second drive transmission portion transmitting the drive force to a document feeding portion, a conveyance portion and a document discharge portion.
