摘要： A transfer device includes an image carrier, a transfer roller, and a moving unit. The moving unit moves the transfer roller between a nip formation state in which the transfer roller forms a transfer nipping portion in contact with the image carrier and a separated state in which the transfer roller is separated from the image carrier. In a contact operation of bringing the transfer roller into contact with the image carrier via the recording medium, the moving unit moves the transfer roller toward the image carrier at a moving velocity slower than that in a pressing operation of generating a predetermined nipping pressure by further moving the transfer roller toward the image carrier after the contact operation. The moving unit causes the recording medium to enter the transfer nipping portion in the contact operation.

摘要： An image forming apparatus includes an image carrier, a transfer member, a power supply, and a control device that controls the power supply to output a DC-AC superimposed bias or a DC bias to transfer a toner image on the image carrier onto a recording medium. The control device controls the power supply to alternately output a first bias being a DC component the same in polarity as the DC bias and a second bias being a DC component opposite in polarity to the DC bias to clean the transfer member when image formation is not taking place. The first bias is output with two target output values including a first value and a second value lower than the first value. The second bias is output with one target output value. An output time of the second bias is longer than an output time of the first bias.

摘要： The probe pin includes a plunger formed of a sheet metal, and a coil spring unit formed of a metal wire and configured to hold the plunger thereon. In a developed state, the plunger includes first and second portions each of which has an upper contact strip, a wide portion, and a lower contact strip, and which are connected to each other via the wide portions formed in the first and second portions. The plunger is formed in a united manner by folding together the first and second portions along a boundary of the wide portions formed therein to thereby bring at least the wide portions into tight contact with each other.

摘要： A belt unit is detachably attached to a housing. A holder changes a state of an endless belt by moving a transfer roller between a first state as an endless belt movement state and a second state as a detachment state. The first state allows the endless belt to circulate for image formation, and the second state allows the belt unit to be detached from the housing. The holder moves the transfer roller adjacent supporter independently of the transfer roller and lifts the opening in the endless belt to a prescribed position to expose it to the front side plate.
