Abstract

According to an image forming apparatus, a simple arrangement is used to switch the transmission of drive forces, produced by drive sources that are used in common by multiple drive mechanisms, without depending on the movement of a carriage, for example. The drive force produced by a line feed (LF) motor to drive feed rollers is transmitted to a pump cam in a recovery system via a pendulum drive force transmission mechanism, which is provided at one end close to the feed rollers. And the drive force produced by another motor to drive paper supply rollers is transmitted via the same pendulum drive force transmission mechanism to the paper supply rollers, or to a blade holder and a cap holder in the recovery system. Therefore, the transmission of the drive forces can be switched by controlling the rotational directions of the motors.
