Abstract: An image forming apparatus is provided with an image forming portion, a collecting duct, a toner collecting device, a toner collecting device, and a first control portion. Into the collecting duct, unnecessary toner generated in the image forming portion flows together with an airflow. The toner collecting device communicates with the collecting duct, has a path of the airflow formed therein, and collects, by using a filter, the toner together with the airflow generated by an airflow generating portion. The first control portion controls an operation condition of a vibrating operation of a vibrating portion that vibrates the filter, in accordance with at least one of setting conditions relating to environment of the image forming portion, a coverage rate of a toner image, the number of printed sheets, and an image density of the toner image.

Abstract: An image forming apparatus includes an image carrying member, a driving device, a charging member, a cleaning member, a voltage applying device, a torque detector for detecting the torque of the driving device, a storage for storing a predetermined torque value Tc, and a control portion. The control portion obtains as Ton the torque when the charging voltage is applied to the charging member and obtains as Toff the torque when no charging voltage is applied to the charging member. Let the torque observed when no charging voltage is applied at an early stage of use of the image carrying member be represented by Toff(0), then, when the relations Toff(0)

Abstract: An image forming device includes an image carrier on the surface of which a toner image is formed, a cleaning member arranged in contact with, for cleaning, the surface of the image carrier, a charging member for electrostatically charging the image carrier, a bias applying device, and a control portion. The bias applying device applies a charging bias having DC and AC biases superimposed on each other to the charging member. The control portion controls the charging bias applied to the charging member by the bias applying device. As the AC bias applied to the charging member, the control portion uses, in a first period from the start of use of the image carrier to a predetermined time thereafter, a first AC bias and, in a second period subsequent to the first period, a second AC bias higher than the first AC bias.
