摘要： An image forming apparatus for forming an image on both of a first side and a second side which are the right side and the back side of recording material, which comprises an image carrier on the surface of which a toner image is formed, a transfer member for forming a transfer part between the transfer member and the image carrier to transfer the toner image on the image carrier onto the recording material, a transfer voltage applying section for applying transfer voltage to the transfer member, a fixing member for heating the recording material, on which the toner image is transferred by the transfer member, passed therethrough to fix the toner image on the recording material, a reversing path for reversing the two sides of the recording material passed through the fixing member and returning the reversed recording material to the transfer part again, a timer section for measuring elapsed time since the recording material, on the first side of which a toner image is transferred, passes through the fixing member until the transfer of a toner image on the second side is started when an image is formed on the first and second sides of the recording material, a humidity detecting section for detecting humidity, and a control section for selecting transfer voltage for transferring a toner image on the second side of the recording material based upon elapsed time measured by the timer section and humidity detected by the humidity detecting section.
摘要翻译：一种用于在作为记录材料的右侧和后侧的第一侧和第二侧上形成图像的图像形成装置，其包括其表面上形成调色剂图像的图像载体，转印构件用于在转印部件和图像载体之间形成转印部分以将图像载体上的调色剂图像转印到记录材料上;转印电压施加部分，用于向转印部件施加转印电压，用于加热记录材料的固定部件，调色剂图像由转印构件转印到其上，将调色剂图像定影在记录材料上，用于反转通过定影构件的记录材料的两侧的反转路径，并将反转的记录材料返回到转印另外，一个计时器部分，用于测量记录材料在其第一侧上传送调色剂图像的经过时间通过固定构件直到在记录材料的第一和第二侧上形成图像时开始第二侧的调色剂图像的转印，用于检测湿度的湿度检测部分和用于选择转印电压的控制部分用于基于由计时器部测量的经过时间和由湿度检测部检测到的湿度，在记录材料的第二侧上传送调色剂图像。

摘要： A recording medium carrier system of an image forming apparatus is constituted by independent units as a paper supply cassette, a paper feed unit, a transfer unit, a fixing unit, and a paper ejecting unit. An intermediate transfer unit in the transfer unit is provided with an intermediate transfer belt to which a toner image formed on a photoconductive drum is primarily transferred at a primary transfer position and which secondarily transfers the toner image on a recording medium at a secondary transfer position, and a driving roller for circulating the intermediate transfer belt. The primary transfer position is arranged close to the driving roller.
