摘要： An image forming apparatus includes a main body portion including an image carrier, an image-carrier driving unit, a latent-image forming unit, a developing-unit attachment section, and a transfer-unit attachment section. The developing-unit attachment section receives a first developing unit having plural developing members or a second developing unit having a single developing member. The transfer-unit attachment section receives a first transfer unit, which includes a first transfer member capable of retaining a recording medium and a first transfer driving unit that rotates the first transfer member, and a second transfer unit, which includes a second transfer member that cannot retain the recording medium. When the first developing unit and the first transfer unit are attached to the developing-unit attachment section and the transfer-unit attachment section, respectively, the first transfer driving unit is mechanically connected to the first developing unit.

摘要： An image forming apparatus includes an image carrier, a transfer body, an elastic layer, a gripper, and a pressing member. The gripper is located in a cutout region in which a cutout is formed. The gripper grips a leading end portion of the recording medium wrapped around the transfer body and releases the leading end portion that is to be separated from the transfer body. At least part of the pressing member is located closer to a trailing-end side of the recording medium than the gripper. The pressing member presses a leading end side of the recording medium, whose leading end portion is gripped by the leading-end gripper, against the elastic layer.

摘要： An image forming apparatus includes an image carrying member, a transfer member, a leading-end holding member, and a trailing-end holding member. The leading-end holding member is mounted on the transfer member and holds, on an outer peripheral surface of the transfer member, a leading-end portion of a recording medium fed to a sheet feeding position that is further upstream than a transfer position in a rotation direction of the transfer member. The trailing-end holding member rotates along the outer peripheral surface. The trailing-end holding member presses the recording medium against the outer peripheral surface while waiting at a waiting position that is further upstream than the transfer position and downstream than the sheet feeding position, and holds a trailing end portion on the outer peripheral surface while rotating together with the transfer member when the trailing end portion of the recording medium arrives at the waiting position.

摘要： An image forming apparatus includes an image carrier, a transfer member, a gripper that grips a leading end portion of a recording medium, and a restraining portion that is disposed so as to face an outer peripheral surface of the transfer member and that is movable relative to the transfer member. The restraining member restrains a trailing end portion of the recording medium that is gripped by the gripper from rising. The restraining portion has widths in a rotational axis direction of the transfer member and in a transport direction of the recording medium and is capable of facing the recording medium in a faceable region, and a part of the faceable region over which the restraining portion faces the trailing end portion of the recording medium is larger than a part of the faceable region over which the restraining member does not face the trailing end portion.
