摘要： A fixing device includes: a plurality of laser irradiation sections each of which emits a laser beam whose wavelength exhibits an absorbance of 80% or more with respect to a corresponding toner; and a control device for controlling the plurality of irradiation sections so that in order to fuse a black toner, (i) a laser irradiation section corresponding to the black toner among the plurality of laser irradiation sections irradiates the black toner with a laser beam thereof, and (ii) the other laser irradiation sections irradiate the black toner with laser beams thereof, where the other laser irradiation sections do not correspond to the black toner among the plurality of laser irradiation sections. Therefore, it is possible to provide a laser fixing device which can fix a color toner while preventing an increase in size of the fixing device as much as possible.

摘要： A fixing device (14) includes a fixing roller (31) which is in contact with an unfixed image formed on a printing medium (91) with toner (93) and a pressure roller (32) which is in contact with the fixing roller (31). The fixing device (14) causes the fixing roller (31) and the pressure roller (32) to sandwich and feed the printing medium (91), so as to fix the unfixed image onto the printing medium (91). The fixing device (14) gives a holding electric field which is an electric field in a direction for holding a reverse polarity toner (92) on the printing medium (91). The reverse polarity toner (92) has a polarity opposite to that of the toner (93) which forms an image on the printing medium. Thus, it is possible to avoid a troulile caused by the adhesion of the reverse polarity toner (92) to the pressure roller (32). Therefore, it is possible to avoid an image failure caused by the reverse polarity toner, maintain a normal image forming operation, and secure a satisfactory image quality and the life of each means even in long-term use.

摘要： A fixer (heater) includes a heat roller and a pressure roller pressing each other. The fixer heats a heated material by passing the heated material through a press region where the heat roller and the pressure roller meet. The fixer further includes an external heat roller heating the pressure roller from outside the pressure roller. A transit time taken for any given point on the heated material to pass through the press region is less than or equal to 2.3×10−2 sec. The surface temperature, T1 (° C.), of the heat roller and the surface temperature, T2 (° C.), of the pressure roller satisfy T1−T2≦100 (° C.), and preferably satisfy T1−T2≦70 (° C.). The load on the heat roller is reduced, and so is the power consumption.

摘要： A fixing device (23) of the present invention includes a fixing roller (131) contacting a toner image surface, and a pressure roller (132) contacting a surface opposite to the toner image surface. In the fixing device (23), a printing sheet (P) on which unfixed toner image is formed passes through a fixing nip portion (Y) where the fixing roller (131) and the pressure roller (132) are in contact with each other, so that the above-described toner image is fixed on the printing sheet (P). The fixing device (23) further includes a control circuit (150) which controls heater lamps (134 to 136) so that a surface temperature of the pressure roller (132) is in a temperature range defined by a cold offset occurring boundary temperature (Thc) of the fixing roller (131) and/or a hot offset occurring boundary temperature (Thh) of the fixing roller (131). With this, it is possible to suppress or prevent a transfer of toner to a pair of rollers (a transfer from the back of the printing sheet to the pressure roller, a transfer from the pressure roller to the fixing roller).
摘要翻译：本发明的定影装置（23）包括与调色剂图像表面接触的定影辊（131）和与调色剂图像表面相对的表面接触的加压辊（132）。在固定装置（23）中，形成有未定影调色剂图像的打印纸（P）通过定影辊（131）和加压辊（132）彼此接触的定影夹持部（Y），使得上述调色剂图像固定在打印纸（P）上。定影装置（23）还包括控制加热灯（134至136）的控制电路（150），使得加压辊（132）的表面温度处于由冷偏移发生的边界温度（Thc）限定的温度范围内）和/或定影辊（131）的热偏移发生边界温度（Thh）。由此，可以抑制或防止调色剂转印到一对辊（从印刷纸的背面到加压辊的转印，从加压辊到定影辊的转印）。
