摘要： An image forming apparatus having a main body whose upper section is split into first and second split lid sections. The first and second split lid sections are arranged to be freely opened and closed. A transfer body and a fixing device are detachably installed in the first split lid section, while a developing device and an image carrying body are installed in the second split lid section. The image carrying body and the transfer body are brought out of contact with each other by opening at least one of the first and second split lid sections. The transfer body and a fixing member are caused to be rotatable by opening the first lid section. With this structure, it is possible to easily repair a paper jam and perform maintenance of the respective sections without increasing the installation space.

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。

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 formed to transfer paper by bringing the transfer paper into contact with the photoreceptor drum, and a pair of register rollers for supplying the transfer paper to the transfer drum at a predetermined time and for curling the transfer paper in an arc. The register rollers include first and second rollers pressed against each other, the first roller being a predetermined hardness and the second roller being a hardness larger than the first roller. The transfer drum is disposed on the same side as the second roller with respect to an imaginary tangent line touching the surface of the second roller at one end of a contact section between the first and second rollers. The image forming apparatus also includes transporting means for supplying the transfer paper to the register rollers so that a front edge of the transfer paper comes into contact with the second roller, temporarily stops, and then continues to the transfer drum. The image forming apparatus also includes a means for changing the pressure that the register rollers are pressed together. Paper type, quality, thickness, and size are detected and the pressure is adjusted accordingly. The means for changing pressure includes a resilient member for the pressing the second roller against the first, and a changing member for changing the amount of deformation of the resilient member.

摘要： An object of the invention is to prevent a silicone gas generated in a fixing unit from entering into a charger. A corona wind rises when the charger corona-discharges, and air is taken in through an outside-air intake. The air flows in through the air passage and the air inlet and flows out through a front opening as an air flow. The silicone gas is isolated by the airflow and prevented from entering into the charger.

摘要： A fixing apparatus and an image forming apparatus of the present invention are arranged so that a fixing control section causes a fixing roller to additionally rotate so that the additional rotation corresponds to a driving delay time also after turning OFF an external heating roller heater when shifting from a temperature raising step in which surface temperature of the fixing roller is raised so as to be equal to a preset fixing temperature to a standby mode and when turning OFF the external heating roller heater and stopping the fixing roller. As a result, it is possible to provide a fixing apparatus and an image forming apparatus in which a surface of a fixing roller is free from deterioration or breakage caused by local heating carried out by an external heating roller.

摘要： A cleaning device includes a cleaning web, a supply roller, a take-up roller, and a control section. Positioned in contact with a circumferential surface of a fuser roller, the web removes toner particles on the circumferential surface. The supply roller has the web wound thereon. The take-up roller takes up the web withdrawn from the supply roller. The control section controls rotation of the take-up roller. The control section performs a first process of causing the take-up roller to take up a first length of the web each time a predetermined taking-up condition is satisfied. The control section also performs a second process, instead of the first process, of causing the take-up roller to take up a second length of the web each time after a first predetermined number of the first processes are performed.
