Abstract: A shielding unit is formed by press-fitting a small diameter portion of a shielding shell into a shielding ring around which an end portion of a shielding member is wrapped, such that the end portion of the shielding member is sandwiched by the shielding ring and the small diameter portion. By having the end portion of the shielding member be folded over to the inside of the shielding ring when press-fitting the small diameter portion of the shielding shell into the shielding ring, even if the position of an opening is unknown, it is possible to reliably position the opening inside the shielding member, unexposed to the outside, after the press-fitting. This easily allows the end portion of the shielding member to be mounted and secured to the shielding shell so as not to be exposed to the outside.

Abstract: An image-forming device includes an image-bearing member, transfer unit, bias applying unit, a pair of conveying rollers, first sensor, second sensor, determining unit, and controller. An image is formed with developer on the image-bearing member. The transfer unit transfers the image formed on the image bearing member onto a sheet of paper at a transfer position located between the image-bearing member and the transfer unit. The bias applying unit applies a transfer bias to the transfer unit. The conveying rollers convey the sheet of paper to the transfer position. The first sensor detects an electrical property of the conveying rollers. The second sensor detects an electrical property of the transfer unit. The determining unit determines a bias for an ambient condition based on the detection results of the first sensor and the second sensor. The controller controls the bias applying unit to apply the bias to the bias applying unit.

Abstract: An image forming apparatus has a transfer unit, a power supply unit that takes a value of a current imparted to the transfer unit as a control target and that supplies power conforming to the value of the control target to the transfer unit; and a determination unit that acquires a detection value of a voltage detection unit and a detection value of a current detection unit and that determines, as a control target value for the power supply unit, an optimum value for the control target derived from a characteristic line showing a relationship between both detection values or a detection value of the voltage detection unit and an optimum value of the control target. The characteristic line is a line showing a relationship of a change in the absolute value of the optimum value for the control target shifting from an increasing tendency to a decreasing tendency with an increase in both detection values or the detection value of the voltage detection unit.
