An image projector includes a first housing, a second housing, a power transmitter, and a heat transporter. The first housing includes a light source to emit light, an image display to form an image with the light from the light source, an illumination optical device to direct the light from the light source to the image display, and a projection optical device to project the image. The second housing includes a power source to supply power, a heat dissipator to dissipate heat, and a cooler to exhaust the heat to an outside of the image projector. The power transmitter couples the first housing and the second housing to each other to transmit the power from the second housing to the first housing. The heat transporter couples the first housing and the second housing to each other to transport heat from the first housing to the second housing.
