摘要： A heating device includes a heating rotator, a pressure rotator, a planar heater, and a holder. The pressure rotator is configured to press against the fixing rotator to form a nip through which the recording medium is conveyed. The planar heater includes a plurality of heat generators arranged side by side and at least one separation region between the plurality of heat generators. The holder holds the planar heater and contacts the planar heater in a pressure direction in which the pressure rotator presses the heating rotator. The holder includes at least one clearance structure configured to cause a contact area between the planar heater and a portion of the holder corresponding to the at least one separation region to be smaller than a contact area between the planar heater and a portion of the holder not corresponding to the at least one separation region.

摘要： A heating device includes a pair of rotators, a heater, a temperature sensor, a conductor, a conductor support, and a component supporting the conductor. The pair of rotators is in contact with each other to form a nip through which a sheet passes. The heater heats at least one of the pair of rotators. The temperature sensor detects a temperature of the heater. The conductor has flexibility and is coupled to the temperature sensor. The conductor support supports the conductor such that a distance from the conductor to at least one position of the heater outside a predetermined region of the heater in a width direction of the sheet is larger than a distance from the conductor to a position of the heater inside the predetermined region in the width direction. The component has a first side facing the heater and a second side opposite the first side.

摘要： A fixing device includes a belt that rotates in a rotation direction and a heater that heats the belt. A conductive member contacts an inner face of the belt and pivots. The conductive member includes one end portion in the rotation direction of the belt, a contact portion that contacts the belt, and an outboard portion that is disposed outboard from the contact portion in the rotation direction of the belt. A holding portion holds the one end portion of the conductive member. A pivot restrictor contacts the outboard portion of the conductive member. The pivot restrictor restricts pivoting of the conductive member about the one end portion of the conductive member.

摘要： A fixing device includes a rotator, a pressure rotator, a heater, and a conductor. The pressure rotator presses the rotator to form a fixing nip between the rotator and the pressure rotator. The heater is in contact with an inner circumferential surface of the rotator and heats the rotator. The conductor is grounded and has a contact portion in contact with a center region of the inner circumferential surface of the rotator in a longitudinal direction of the rotator.

摘要： An image forming apparatus includes multiple image forming units each accommodating an image bearer and a developer bearer to develop a latent image formed on the image bearer. Each of the image forming units other than a prescribed image forming unit runs in an ordinary reverse rotation mode, in which at least one of the image bearer and the developer bearer rotates in an opposite direction during a non-image formation time period. The prescribed image forming unit runs in a special reverse rotation mode, in which at least one of the image bearer and the developer bearer rotates in the opposite direction during the non-image formation time period based on a differentiated one of a rotation time period, a start timing, a rotational speed, and a frequency of operation from those of the other image forming units, or does not run in the special reverse rotation mode.

摘要： A conveying device conveys a sheet of non-blank recording medium recorded with an image formed in an image forming unit, and includes a container that is detachable and contains a sheet of blank recording medium, a feeding unit that feeds the blank recording medium from the container, and a recirculating path that leads the non-blank recording medium to the feeding unit. The recirculating path is disposed lateral to the image forming unit. A part of the recirculating path is integrated into the container and forms a reversing path that leads to the feeding unit. At least one of surfaces of the reversing path can be exposed.

摘要： A pressure switching mechanism includes a rotatable support, a biasing member, and a switching rotation member. The rotatable support rotates around a first rotation shaft to support a contact member such that the contact member is movable in a direction toward or away from a contacted member. The biasing member has one end connected to a biased portion of the rotatable support, which is located on a side opposite the first rotation shaft with respect to a virtual line passing through a contact portion between the contact member and the contacted member, and applies a biasing force to the rotatable support. The switching rotation member is connected to another end of the biasing member opposite the one end of the biasing member, rotates around a second rotation shaft, and has a rotation operating end which is on a side opposite the second rotation shaft with respect to the virtual line.
