Abstract: An image forming apparatus includes plural rotating members that are rotatable; an annular circulating member that is wound around the plural rotating members and circulates when the rotating members rotate; a retaining member attached to an attaching portion of the circulating member and that circulates together with the circulating member, the retaining member being configured to retain a recording medium in an area where the attaching portion comes into contact with one of the rotating members; an image forming section that forms an image on the recording medium at an image forming position defined on a circulation path along which the circulating member circulates; a delivering unit that delivers the recording medium to a retaining position where the recording medium is to be retained by the retaining member; a detector that detects rotation of the one rotating member; and a controller that controls delivery of the recording medium from the delivering unit to the retaining position, the delivery being controlled with reference to information detected by the detector.

Abstract: An image forming apparatus includes: a circulating member that is a part of a transport path that transports a recording medium; a holding member that is fixed to the circulating member, circulates, and holds a leading end portion of the recording medium; an image forming section that forms an image on the recording medium at an image forming position in a circulation path of the circulating member; and a feeding section that feeds out the recording medium to a holding position where the holding member holds the leading end portion of the recording medium. When a circulation velocity Vg is defined as a velocity at which the circulating member circulates the holding member, a transport velocity of the recording medium is reduced from a first transport velocity V1, which is higher than the circulation velocity Vg, to a second transport velocity V2, which is lower than the first transport velocity V1, before the leading end portion of the recording medium enters the holding position.

Abstract: An image forming apparatus includes: a fixing cylinder, having a groove formed in an outer portion thereof in a rotational radial direction thereof; a delivery cylinder; plural holding members configured to hold a recording medium when it passes around the delivery cylinder toward the fixing cylinder, and arranged in a length direction of a circulating member, each holding member being disposed in the groove when the holding member passes along the outer portion of the fixing cylinder; and a pressure unit applying a pressure to the recording medium as it passes between the pressure unit and the fixing cylinder, the pressure unit coming into contact with an end portion of the groove in a rotation direction of the fixing cylinder before or after a period during a holding operation when one of the holding members holds the recording medium.

Abstract: A detection device includes a first detection unit that detects a leading edge portion and a trailing edge portion of a medium before the medium is heated, and a second detection unit that differs from the first detection unit and that detects the leading edge portion and the trailing edge portion of the medium after the medium is heated.

Abstract: A detection device includes: a transport unit that stops transportation of a medium on which a first image is formed, the transport unit restarting the transportation of the medium toward an image forming unit after the medium has been in a stopped state, the image forming unit forming a second image on the medium; and a detection unit that detects an edge portion of the medium while the medium is in the stopped state.

Abstract: A transport device includes: a rotating member that rotates; a circulating member that is loop-shaped and wrapped around the rotating member, the circulating member being circulated by rotation of the rotating member; and a pair of pinching members attached to an attachment portion of the circulating member and circulated together with the circulating member, the pair of pinching members changing from a separated state, in which the pair of pinching members are separated from each other, to a closely positioned state to pinch a transport object that has entered a space between the pair of pinching members in the separated state. The attachment portion of the circulating member is in contact with the rotating member when the transport object starts to enter the space between the pair of pinching members in the separated state.

Abstract: A transport device includes a rotating member that rotates; a circulating member that is loop-shaped and wrapped around the rotating member, the circulating member being circulated by rotation of the rotating member; a pair of pinching members attached to the circulating member and circulated together with the circulating member, the pair of pinching members changing from a separated state, in which the pair of pinching members are separated from each other, to a closely positioned state to pinch a transport object that has entered a space between the pair of pinching members in the separated state; and a guide unit positioned to overlap the pair of pinching members in the separated state when viewed in one direction along a rotational axis direction of the rotating member, the guide unit guiding the transport object into the space between the pair of pinching members in the separated state.
