時間／日入れておく使い方の場合、約１〜２年でファン
を交換しなげればならないという欠点があった。(1) In the case of a system that operates constantly in conjunction with the equipment power supply, the fan life is usually approximately 10,000 to 20,000 hours, and the fan life is approximately 10,000 to 20,000 hours.
If the fan is used in an hour/day mode, there is a drawback that the fan must be replaced every 1 to 2 years.
（２）装置が記録動作中のときだけ動作させる方式の場
合
記録動作終了後、装置内部の比熱の影響により、蓄積さ
れた熱量の外部への放出ができなくなってしまい、装置
内温度が上昇してしまうという欠点があった。(2) In the case of a system that operates only when the device is in recording operation After the recording operation is completed, the accumulated heat cannot be released to the outside due to the influence of the specific heat inside the device, causing the temperature inside the device to rise. There was a drawback that

和されて帯電電位が下がる。The photosensitive drum 2 is rotated in the direction of an arrow l9 by a main motor 17 via a drive system (not shown). Also,
Since the sections from the charger 3 to the developer 5 are shielded from external light, the surface of the photoreceptor drum 2 charged by the charger 3 retains its charge, and the portion 20 of the photoreceptor drum 2 is exposed to the exposure means. 4, the charge is neutralized only in the exposed portion, and the charged potential is lowered.
此処で、感光体ドラム２上の静電潜像は、現像器５によ

１上に定着される。This toner image is transferred onto the transfer paper 1l by the transfer charger 6, and a record can be obtained on the transfer paper 11. The toner remaining on the photoreceptor drum 2 after transfer is scraped off by a cleaner 7, and the residual potential on the photoreceptor drum 2 is removed in a static elimination exposure section 8, after which the second process begins in the same manner. Further, the toner image on the transfer paper 11 is sandwiched between a heat roller 13 and a backup roller 14 in the fixing device 9 and is conveyed in the direction of an arrow 21. At this time, the toner image is transferred to the transfer paper 1 by applying heat from the heat roller 13.
