摘要： A fixing device includes a fixing rotator that rotates and includes an inner face. A pressure rotator is disposed opposite the fixing rotator and rotates. A nip former sandwiches the fixing rotator together with the pressure rotator to form a nip between the fixing rotator and the pressure rotator. The nip former includes an outer face disposed opposite the inner face of the fixing rotator. The inner face of the fixing rotator and the outer face of the nip former sandwich a lubricant. At least one of the inner face of the fixing rotator and the outer face of the nip former includes a projection having a volume smaller than 0.3 ml/m2 and a recess having a spatial volume greater than 0.08 ml/m2. The volume and the spatial volume are three-dimensional surface roughness parameters, respectively, defined by the International Organization for Standardization 25178 standard in an initial state before the fixing rotator rotates.

摘要： A fixing device includes a heat generator being disposed inside a loop formed by a rotator and including a heat generating portion to radiate radiant heat. A reflector is disposed inside the loop formed by the rotator and includes a reflection face to reflect the radiant heat radiated from the heat generator toward the rotator. A support supports the reflector. A holder holds each lateral end of the support in a longitudinal direction of the support, which is perpendicular to the rotation direction of the rotator. A fastener attaches the reflector to the support at an attachment position disposed at each lateral end of the reflector in a longitudinal direction of the reflector. The attachment position is disposed outboard from a lateral edge of the heat generating portion of the heat generator and disposed inboard from the holder in the longitudinal direction of the reflector.

摘要： A fixing device includes a nip formation pad to press against a fixing rotator. A primary heater is disposed opposite the fixing rotator in a primary heating span spanning in an axial direction of the fixing rotator to heat the primary heating span of the fixing rotator from which heat is conducted to the nip formation pad with a primary conduction. A secondary heater is disposed opposite the fixing rotator in a secondary heating span that is outboard from the primary heating span in the axial direction of the fixing rotator. The secondary heater is interposed between a first nip formation portion and a second nip formation portion of the nip formation pad to heat the secondary heating span of the fixing rotator through the nip formation pad from which heat is conducted to the fixing rotator with a secondary conduction greater than the primary conduction.

摘要： A transfer fixing device includes a transfer fixing member, a pressure member, and a primary heater. The transfer fixing member defines a moving surface on which a toner image travels. The pressure member is pressed against the transfer fixing member to define a transfer fixing nip where the toner image traveling along the moving surface meets a surface of a recording medium traveling along the media conveyance path. The primary heater is located upstream of the transfer fixing nip along the media conveyance path to heat the surface of the recording medium before entering the transfer fixing nip. The heated surface of the recording medium fuses toner for transfer and fixing into place at the transfer fixing nip. The pressure member is at least partially electrically biased to generate an electrostatic field to promote transfer of toner at the transfer fixing nip.
