Abstract

Official abstract text for this publication.

There is provided an image forming apparatus including a driving source, a switchback roller which switches between a normal rotation direction and a reverse rotation direction, first and second gear train for rotating the switchback roller in the normal and reverse rotation directions, respectively, a switching mechanism which switches among a first mode for transmitting driving force to the first gear train, a second mode for transmitting the driving force to the second gear train, and a third mode for not to transmit the driving force, a switching element which switches between a first state allowing switching of the switching mechanism into the first or third mode and a second state allowing switching of the switching mechanism into the second mode; and a controller which controls a state change of the switching element between the first state and the second state.

First claim

Opening claim text (preview).

What is claimed is: 1. An image forming apparatus comprising: a driving source configured to generate a one-direction rotational driving force; a switchback roller configured to be switched between a normal rotation direction and a reverse rotation direction for switching a conveyance direction of a recording medium having an image formed thereon by an image forming unit; a first gear train configured to transmit the one-direction rotational driving force of the driving source…
