Image forming apparatus and image forming method

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.

Image forming apparatus and transfer device having attachable developing unit

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.

Image forming apparatus with leading-end and trailing-end holding members to prevent sagging of recording medium during transportation

A transfer device includes a transfer body that transports a recording medium to a transfer position to transfer toner images to the recording medium; a leading-end gripping member that grips a leading-end portion of the recording medium when causing the recording medium to be wrapped around the transfer body and releases the leading-end portion when causing the recording medium that has been wrapped around the transfer body to become separated from the transfer body; and a moving member that moves, after a final toner image starts being transferred to the recording medium but before the leading-end gripping member releases the leading-end portion, the leading-end gripping member while the leading-end gripping member grips the leading-end portion in order to cause a leading-end side of the recording medium to become separated from the transfer body.
