摘要： It is intended to provide an image forming apparatus capable of conducting charge adjustment of post-transfer residual toner appropriately by securing a contact area of a temporarily-collecting member and an electrode, without applying excessive deformation load to the temporarily-collecting member. There are arranged a brush roller for temporarily collecting post-transfer residual toner, and an electrode of which inwardly-curved face being in contact with the brush roller in a toner charge apparatus. Thereby, charged-in-opposite-polarity toner, out of post-transfer residual toner, is collected by the brush roller, polarity of the toner is reversed to original polarity, and then, returned to a photosensitive drum. The inner face of the electrode, i.e., a contact face of the electrode and the brush roller is formed in an inwardly-curved face. Thereby, a large contact area and light pushing force of the electrode to the brush roller can go together.

摘要： In order to conform a specific correction table to the characteristics of a liquid developer to be used, the specific correction table is created by calibrating a standard correction table stored in advance by using a viscosity property value of a liquid developer for calibration at a current temperature. A concentration adjustment is performed by comparing a measured viscosity property value with a target viscosity property value which is temperature-corrected based on the specific correction table. Further, the viscosity property value of a liquid developer is detected by measuring the current of a motor for stirring the liquid developer, where a no-load stirring current value is measured in the absence of a liquid developer, and one or both of a measured current value and target current value is corrected based thereon.
