摘要： In an image forming apparatus, exhaust fans of a ventilation device and an intake port of an air purifier are provided on side wall portions respectively that are opposite each other in a main casing of the image forming apparatus, and the exhaust fans of the ventilation device are provided in a location higher than the intake port of the air purifier. With this configuration, silicone that is discharged from the exhaust fans of the ventilation device is almost never suctioned into the intake port of the air purifier, such that almost none of this silicone adheres to a discharging electrode of the ion generator, and an ion generating efficiency of the ion generator can be maintained over a long period without dropping.

摘要： An image forming apparatus of the present invention includes a photoreceptor drum on which a toner image is formed, a transfer drum for transferring the toner image to paper by bringing the paper into contact with the photoreceptor drum, the transfer drum having a dielectric layer, a semi-conductive layer and a conductive layer laminated in this order from the paper side, a power source which is connected to the conductive layer so as to apply a predetermined voltage to the conductive layer, and a conductive roller for pressing the paper against a surface of the dielectric layer so as to produce a potential difference between the conductive layer and the paper. The potential difference induces charges of the same polarity as the voltage applied to the conductive layer on the surface of the dielectric layer, and charges of the opposite polarity on a back surface of the paper pressed against the surface of the dielectric layer. Thus, the paper electrostatically adheres to the transfer drum in a satisfactory manner. Moreover, unlike charging by atmospheric discharge, since the surface potential of the transfer drum is stable, it is possible to prevent unsatisfactory transfers and improve the image quality.
摘要翻译：本发明的图像形成装置包括其上形成有调色剂图像的感光鼓，用于通过使纸与感光鼓接触而将调色剂图像转印到纸张上的转印鼓，转印鼓具有介电层，半导电层和导电层，从纸侧依次层叠，连接到导电层以向导电层施加预定电压的电源，以及用于将纸压在表面上的导电辊以产生导电层和纸之间的电位差。电位差引起与施加到电介质层表面上的导电层的电压相同极性的电荷，并且在压在电介质层表面上的纸的背面上的相反极性的电荷。因此，纸以令人满意的方式静电粘附到转印鼓上。此外，与通过大气排放的充电不同，由于转印鼓的表面电位稳定，可以防止不令人满意的转印并提高图像质量。
