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 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.
