Abstract
A drive transmission device includes a plurality of drive transmission units and a heat-resistant member. The drive transmission units include a plurality of drive transmission mechanisms to transmit drive force from a plurality of drive sources to a driven member. At least two drive sources of the drive sources are included in at least two drive transmission units of the drive transmission units. The at least two drive sources are disposed at substantially a same height and on a same side with respect to at least two drive transmission mechanisms of the drive transmission mechanisms that correspond to the at least two drive sources. The heat-resistant member is disposed at a position higher than the at least two drive sources in a use state. The at least two drive transmission mechanisms are shielded from the at least two drive sources by the heat-resistant member at the position.
