摘要： An image forming apparatus operable in a duplex print mode includes an image carrier and an image transferring device including a first and a second intermediate image transfer body whose surfaces are movable in contact with each other while forming a nip therebetween. Toner images are respectively transferred to opposite surfaces of a sheet using two pairs of conductive rollers that face each other via the first and second intermediate image transfer bodies at a nip. Two of the conductive rollers associated with the second intermediate image transfer body are transfer rollers respectively applied with one and the other of biases of opposite polarities.

摘要： An image forming apparatus for recording on two sides in a single pass, with which the transfer of a toner image onto one side of a recording medium and the transfer of a toner image onto the other side can both be performed under optimal conditions, which results in an increase in image quality. Contact-type transfer rollers are used as secondary and tertiary transfer means, so unlike with a transfer charger (a non-contact type of transfer means), there is no discharge product. A toner image that has been once transferred from an image support onto a recording medium is prevented from being retransferred back onto the image support, and a toner image that has been transferred onto the recording medium by the action of a first transfer member is prevented from being retransferred to the image support when a toner image is transferred onto the recording medium by the action of a second transfer member.

摘要： A method of controlling the density of images produced by an electrophotographic image forming apparatus to a constant value. A toner density sensor is provided with a first reference level variable in response to the output of an image density sensor, and a second reference level representative of a state associated with the optimum condition of a developer (e.g. immediately after replacement thereof). During usual control, the toner concentration of the developer is detected on the basis of the output of the toner density sensor, and the toner supply to the developer is controlled on the basis of the result of comparison of the detected toner concentration and the first reference level.

摘要： A method applicable to an image forming apparatus which is implemented by an electrophotographic procedure for maintaining that the density of images to be produced by the apparatus is adequate at all times. When the density of a toner image of a reference image or a predetermined pattern sensed by the image density sensor lies in a predetermined adequate range, a sensing level associated with the toner density sensor responsive to the toner density of a developer is not changed. When the density of the toner image does not lie in the adequate range, it is determined that at least the sensing level of the toner density sensing being used at that time has to be changed. Then, whether or not the sensed density of the toner image of the reference image exists in a range in which the image density is controllable is determined. If the sensed density lies in the controllable range, the sensing level of the density sensor being used at that time is suitably changed in response to the sensed density of the toner image. If otherwise, i.e., when the image density sensor is in a fault, toner density control is continued without changing the sensing level of the toner image sensor being used.
摘要翻译：适用于通过电子照相程序实现的图像形成装置的方法，用于保持由设备产生的图像的密度始终是足够的。当参考图像的调色剂图像的浓度或由图像浓度传感器感测到的预定图案的浓度处于预定的适当范围时，响应于显影剂的调色剂浓度的与调色剂浓度传感器相关联的感测水平不改变。当调色剂图像的浓度不在适当的范围内时，确定至少要在此时使用的调色剂浓度感测的感测电平必须改变。然后，确定参考图像的调色剂图像的感测密度是否存在于图像浓度可控制的范围内。如果检测到的密度位于可控范围内，则响应于感测到的调色剂图像的密度，适当地改变当时使用的密度传感器的感测电平。否则，即当图像浓度传感器处于故障时，调色剂浓度控制继续进行，而不改变所使用的调色剂图像传感器的感测电平。
