Abstract: Provided is a chemical compound represented by the general formula (A), in which each of substituents Q1 to Q6 is bonded to a nitrogen atom of melamine backbone. In the general formula (A), at least one of Q1 to Q6 is X, and at least one of Q1 to Q6 is Y. R1 is a hydrogen atom or an alkyl group having 1 to 12 carbon atoms. R2 is a hydrogen atom, or a monovalent hydrocarbon group selected from the group consisting of an alkyl group having 1 to 12 carbon atoms, an aryl group having 6 to 25 carbon atoms, and an aralkyl group having 7 to 30 carbon atoms. Each of R51 and R52 is a divalent organic group, and a is an integer of 1 to 3.

Abstract: A fixing device includes a belt, a pad, a pressure rotator, a lubricant supplier, and a collector. The belt forms a loop. The pad is inside the loop of the belt and contacts the belt. The pressure rotator presses the belt against the pad to form a fixing nip between the belt and the pressure rotator. The lubricant supplier supplies lubricant to an inner face of the belt. The collector collects the lubricant. The collector has a first end and a second end. The first end contacts an inner face of one end of the belt in a width direction of the belt. The second end contacts the inner face of another end of the belt opposite to the one end in the width direction.

Abstract: A fixing device includes a rotatable endless belt, a pressure rotator, a heating rotator, a pad, an intermediate member, and a holder. The pad is disposed inside a loop of the endless belt and pressed by the pressure rotator to form a fixing nip portion between the endless belt and the pressure rotator. The intermediate member has a pad abutment portion to abut on the pad at a fixing nip facing portion of the pad. The holder holds the pad and the intermediate member, and has an intermediate member abutment portion to abut on a pad facing portion of the intermediate member. The pad has a recess in the fixing nip facing portion. The pad abutment portion abuts on the fixing nip facing portion and covers the recess in at least a part of the fixing nip portion corresponding to a passage region of a recording medium.

Abstract: A fixing device includes a tubular rotator and a first heater disposed inside the tubular rotator and extended in a longitudinal direction of the first heater. The first heater heats the tubular rotator. A second heater is disposed inside the tubular rotator and extended in a longitudinal direction of the second heater. The second heater heats the tubular rotator. A heating adjuster is interposed between the first heater and the second heater. The heating adjuster adjusts heat conduction from the first heater to the second heater. A joint combines the heating adjuster with the second heater.

Abstract: A fixing device includes a fixing belt that is endless and rotatable in a rotation direction and a nip former stretching the fixing belt and including an elastic layer as a surface layer. A pressure rotator presses against the nip former via the fixing belt to form a fixing nip between the fixing belt and the pressure rotator, through which a recording medium is conveyed. A presser is disposed downstream from an exit of the fixing nip in a recording medium conveyance direction. The presser brings the fixing belt into contact with the pressure rotator.
