摘要： A laser scanning device includes a light source (331), a rotary polytope (332), a motor (333), a bearing (333D), and a detection processing portiont (53). The rotary polytope (332) scans light emitted from the light source (331). The motor (333) rotates the rotary polytope (332). The bearing (333D) rotatably supports a rotation shaft (333A) of the motor (333). The detection processing portiont (53), in a case where the motor (333) is driven at a first speed that is higher than a predetermined reference speed, performs detection of an abnormal state based on an atmospheric temperature detected at a position located within a predetermined first range from the bearing (333D), and in a case where the motor (333) is driven at a second speed that is lower than the reference speed, does not perform the detection of the abnormal state, wherein the abnormal state is a state where the temperature of the bearing (333D) has exceeded a predetermined allowable temperature.

摘要： An image forming apparatus (1) includes an image forming section(300), a housing (10), an image scanning section (3B), an airflow generation section(12Lb), a guiding air path (126), and a blow-off port (125). The image forming section (300) forms an image on a sheet. The housing (10) accommodates the image forming section (300) therein. The image scanning section (300) has a bottom portion (35) and is disposed above the housing (10). The airflow generation section (12Lb) generates an airflow inside the housing (10). The guiding air path (126) guides the airflow upward inside the housing (10). The blow-off port (125) is communicated with the guiding air path (126) and arranged so as to face the bottom portion (35) of the image scanning section (300).

摘要： An image forming apparatus (1) includes an exhaust duct (100) to guide air inside the image forming apparatus (1) to an outside of the image forming apparatus (1). A positive ion generator (105) emits a positive ion into the exhaust duct (100). A negative ion generator (104) emits a negative ion into the exhaust duct (100). The negative ion generator (104) is shifted from the positive ion generator (105) in one of an air flow direction of the air moving inside the exhaust duct (100) and a direction perpendicular to the air flow direction.

摘要： A fixing device (5) includes an auxiliary duct (60). The auxiliary duct is provided between a cover member (47) attached to a coil bobbin (38) so as to cover a magnetic core (39) and a coil (37), and a core holder (45) provided opposing to the coil bobbin, to which the magnetic core is attached. The auxiliary duct communicates with an intake hole (47a) provided at one end in a longitudinal direction of the cover member, and has opening holes (60e) overlapping with some of holder opening portions (45c) formed on the core holder. The fixing device causes air to flow into between the core holder and the coil bobbin via the auxiliary duct and the holder opening portions from the intake hole, and discharges the air warmed by heat of the coil from an exhaust hole formed at the other end of the cover member, thereby adjusting the flowing amount of air in a longitudinal direction of the coil.
