摘要： A fixing device includes a first rotator, a second rotator, a heater, a separator, and a resistor. The second rotator is in contact with an outer circumferential surface of the first rotator to form a nip through which a recording medium bearing an unfixed image passes. The heater includes a heat generator and heats the first rotator. The separator is in contact with an outer circumferential surface of the first rotator and separates the recording medium passing through the nip from the first rotator. The resistor couples the second rotator and the separator to the ground.

摘要： A fixing device includes a first rotator, a second rotator, a heater, and a discharger. The first rotator includes a conductive first layer, a non-conductive second layer, and a conductive third layer. The first to third layers exist in an order of the first layer to the third layer from a center of the first rotator to an outside of the first rotator. The second rotator forms a nip between the first rotator and the second rotator. A recording medium bearing a toner image passes through the nip. The heater is disposed inside a loop of the second rotator and heats the second rotator. The discharger is in contact with the first layer and the third layer and removes electric charge from the first rotator.

摘要： A fixing device includes a fixing rotator, a heater, a pressure rotator, a stay, a biasing member fixed to the stay, and a nip formation pad. The nip formation pad is supported by the stay, disposed inside the fixing rotator, and forms a nip. The nip formation pad includes at least one engaged portion at a position other than both ends of the nip formation pad or engaged portions at both ends of the nip formation pad. The at least one engaged portion engages an engaging portion in the stay to generate a first rotational moment. The engaged portions at both ends engage engaging portions in the stay to generate a second rotational moment. Each rotational moment is smaller than a rotational moment generated by engagement between an engaging portion in the stay and an engaged portion at only one end of the nip formation pad.

摘要： A driver includes a first rotator, a second rotator, a bearing, a housing, a drive gear, a first idler gear, a pivot member, and a second idler gear. The first idler gear is meshed with the drive gear. The pivot member rotates around a rotation center axis in the housing and includes an idler gear support portion rotatably holding the first idler gear. The second idler gear is meshed with the first idler gear and disposed on the rotation center axis of the pivot member. A rotation center of the pivot member is present in a region outside a circle having a diameter of 1.5×L and inside a circle having a diameter of 1.8×L around a rotation center of the first idler gear, when a distance between a rotation center of the first rotator and the rotation center of the first idler gear is L.

摘要： An image forming apparatus includes a pressing device, an apparatus body, an opening body, and a vibration insulator. The pressing device housed in the apparatus body is configured to press a pressing body to a pressing target body. The opening body is configured to open and close to the apparatus body. The opening body presses a pressing target portion of the apparatus body, at a first pressing portion to cancel a pressing state of the pressing device by opening of the opening body and at a second pressing portion to enter the pressing state of the pressing device by closing of the opening body. The vibration insulator is provided on at least one of the pressing target portion and the second pressing portion, at a contact portion at which the pressing target portion contacts the second pressing portion when the first pressing portion cancels the pressing state.

摘要： A separator for separating a recording medium from a fixing rotator includes a separation body including a front end and a conveyance path side face. The front end is disposed in proximity to an outer circumferential surface of the fixing rotator. The conveyance path side face faces a conveyance path where the recording medium is conveyed. At least one rotary separation aid projects beyond the conveyance path side face of the separation body toward the conveyance path. The rotary separation aid is rotated by the recording medium as the recording medium comes into contact with the rotary separation aid.

摘要： In the production management system, supervisors of manufacturing and production check section, component check section, and manufacturing technical section set retrieval conditions for retrieving data stored in a database of a step-monitoring server in order to obtain information on daily, hourly and monthly statuses of products in the production management system by using output system clients. The input retrieval conditions are transmitted to the step-monitoring server. Data matching with these retrieval conditions are retrieved from the database of the step-monitoring server. The retrieved data is chronologically processed and displayed on screens of the clients which requested the data.

摘要： A manually operated dot printer designed for use in a pocket-sized calculator or a small-sized electronic device includes a printing head which is manually driven across the dot printer paper in one direction to store energy in springs. The springs return the printing head in steps intermittently while the printing head effects printing on the printing paper. The springs also feed the printing paper. While the printing head is manually moved, the printing elements are maintained out of contact with the printing paper. During return movement of the printing head, the printing elements are in contact with, or nearly in contact with, the printing paper for printing operations. The actual printing operations of the printing head are performed with electrical control using elements of low power consumption.

摘要： A heating device includes a heater, a safety device, and a holder. The safety device has a heat-sensitive surface facing the heater. The safety device cuts off power supply to the heater in response to reaching a temperature of the heat-sensitive surface to be equal to or higher than a predetermined temperature. The holder holds the heater. The holder has a through hole that opens toward the heater and includes a step portion disposed on an inner circumferential surface of the through hole. The step portion supports an end of the heat-sensitive surface such that a central portion of the heat-sensitive surface of the safety device is not in contact with the heater.
