An image fixing apparatus has a heating member, a back-up roller cooperating with the heating member to form a nip therebetween for pinching and conveying a recording material bearing an image thereon, and a controlling device for controlling a temperature of the nip. The controlling device heats the nip after a fixing process is finished and after a rotation of the back-up roller is stopped.

The present invention provides a fixing apparatus with a pair of fixing members at least one of which is rotatable, a nip being formed between the fixing members and a recording material which carries a non-fixed toner being conveyed through the nip and heated at the nip to fix the non-fixed toner onto the recording material. The apparatus has a cleaning mode for cleaning the fixing member, in which a sheet is pinched by the nip, and the sheet is conveyed in a direction by repeating rotation and stoppage of the rotatable fixing member.

An image heating apparatus for heating a toner image formed on a recording material is constituted by a roller contactable with a toner image carrying surface of the recording material; a heating member for heating the roller, the heating member contacting a surface of the roller, wherein the toner image formed on the recording material is heated in contact with the roller; and a driving mechanism for moving the heating member to a first position contacting the roller and a second position, contacting the roller different from the first position with respect to a tangential direction of the roller.
摘要:
A heater, or an image heating apparatus including the heater includes a substrate, heat generating resistors formed at least in a cycle path on the substrate, and current supply electrodes provided at electrical ends of the heat generating resistors, wherein plural heat generating resistors are connected in parallel to at least one of the current supply electrodes. Thus there can be obtained a heater having excellent heat generating characteristics even in a compact dimension and an image heating apparatus utilizing such heater.

Provided is an Mg alloy and a method for producing same able to demonstrate high strength without requiring an expensive rare earth element (RE). The high-strength Mg alloy containing Ca and Zn within a solid solubility limit and the remainder having a chemical composition comprising Mg and unavoidable impurities is characterized in comprising equiaxial crystal particles, there being a segregated area of Ca and Zn along the (c) axis of a Mg hexagonal lattice within the crystal particle, and having a structure in which the segregated area is lined up by Mg3 atomic spacing in the (a) axis of the Mg hexagonal lattice. The method for producing the high-strength Mg alloy is characterized in that Ca and Zn are added to Mg in a compounding amount corresponding to the above composition and, after homogenization heat treating an ingot formed by dissolution and casting, the above structure is formed by subjecting the ingot to hot processing.

Provided is a radio-controlled watch capable of performing leap second correction even when information on a leap second is not received from a satellite. Provided is a radio-controlled watch that adjusts time by receiving a signal containing time information from a satellite, the radio-controlled watch being configured to: store a leap second correction value to be used for leap second correction with respect to the time information; display a numerical value corresponding to the leap second correction value; receive an instruction operation of changing the leap second correction value from a user in a state in which the numerical value is displayed; and change the leap second correction value in response to the received instruction operation.
