摘要： An image foaming apparatus includes an image bearing member, a transfer unit, and a pressing mechanism. The image bearing member bears a toner image. The transfer unit is disposed opposite the image bearing member and is swingably and detachably held within a main body of the image forming apparatus. The transfer unit includes a transfer member and a power receiving electrode. The transfer member is disposed opposite the image bearing member, to contact the image bearing member to form a transfer nip therebetween and transfer the toner image on the image bearing member onto a recording medium in the transfer nip. The power receiving electrode receives power from the main body of the image forming apparatus. The pressing mechanism presses the transfer unit against the image bearing member and includes a power supply electrode that contacts the power receiving electrode of the transfer unit to supply power thereto.

摘要： A transfer assembly includes a counter member having a contact face, an engagement/disengagement unit to engage and disengage the image carrying face of image carrying member and the contact face of counter member using a cam, a pressure device to apply force to a transfer nip between the image carrying face and contact face, and a recording medium feed device to feed the recording medium to the transfer nip. When the cam is at a first rotation position, the image carrying face and contact face are separated, and when the cam is at a second rotation position, the image carrying face and contact face contact. Before the recording medium enters the transfer nip, the cam rotates from the first rotation position toward the second rotation position. After the recording medium enters the transfer nip, the cam is at the second rotation position to press the image carrying face with the contact face.
