A transfer apparatus includes a transfer unit, a detector, a supplying unit, and a controller. The transfer unit transfers a toner image onto an object onto which transfer is to be performed. The detector detects humidity. The supplying unit includes a constant voltage supplying unit that supplies a transfer voltage that is a constant voltage to the transfer unit, and a constant current supplying unit that supplies a transfer current that is a constant current to the transfer unit. The controller controls the supplying unit such that the transfer voltage is supplied from the constant voltage supplying unit to the transfer unit when transfer is performed in a case where the detected humidity is not greater than a threshold, and the transfer current is supplied from the constant current supplying unit to the transfer unit when transfer is performed in a case where the detected humidity exceeds the threshold.

Transfer apparatus, non-transitory computer readable medium, and image forming apparatus

A transfer apparatus includes a transfer unit, a first detector, a supplying unit, a second detector, and a controller. The transfer unit transfers a toner image onto an object. The first detector detects humidity. The supplying unit supplies, to the transfer unit, a transfer voltage, a setting voltage in a first case, and a setting current in a second case. The second detector detects a current flowing through the transfer unit upon supply of the setting voltage and a voltage across the transfer unit upon supply of the setting current. The controller controls the supplying unit such that, when transfer is performed in the first case, a transfer voltage derived using the setting voltage and the detected current is supplied, and when transfer is performed in the second case, a transfer voltage derived using the setting current and the detected voltage is supplied to the transfer unit.

A transfer device includes an endless intermediate transfer belt that moves circularly, a first rotating body pressed into contact with the inner surface of the belt, and a second rotating body disposed at a position facing the first rotating body to contact with the outer surface of the belt. The belt includes a first pressing section that is in contact with the second rotating body due to a first pressure from the first rotating body such that a toner image that has been first-transferred to the outer surface of the belt is second-transferred onto a recording medium that passes between the belt and the second rotating body and a second pressing section that is in contact with the second rotating body due to a second pressure smaller than the first pressure on the upstream side of the first pressing section in the belt movement direction.

Transfer device and image forming apparatus

An intermediate transfer device includes an intermediate transfer member, intermediate transfer member support members, and two frame members each including first and second positioning members each having a positioning portion. At least one of the frame members satisfies a condition L:L=2.85:x 0&#x2266;x&#x2266;1, where Lis the length of a line segment connecting an intersection point to the positioning portion of one of the positioning members on a side opposite to a side toward which a line of action of a force applied by a second-transfer unit is inclined and Lis the length of a line segment connecting the intersection point to the positioning portion of the other of the positioning members on the side toward which the line of action is inclined, the intersection point being an intersection of the line of action and a line segment connecting the positioning portions.

Intermediate transfer device and image forming apparatus including frame members

An image forming apparatus includes an image forming unit that forms an image to be formed on a recording medium. The image formed by the image forming unit has a size larger than a size of the recording medium that is transported, the image forming unit causing the image to adhere to the entire area of the recording medium. A width of the image in a direction substantially orthogonal to a transporting direction of the recording medium increases from a front end toward a rear end of the recording medium in the transporting direction of the recording medium.
