1. A light emitting chip comprising:
a light emitting unit array including a plurality of light emitting units arranged in a predetermined direction;
an image data input terminal configured to be input with image data;
a first data storage unit configured to store data, input from the image data input terminal, for causing a first light emitting unit included in the plurality of light emitting units to emit light;
a second data storage unit configured to store data, input from the image data input terminal, for causing a second light emitting unit included in the plurality of light emitting units to emit light;
a signal output unit configured to output a first trigger signal and a second trigger signal delayed with respect to the first trigger signal; and
a drive unit configured to drive the first light emitting unit, in a case where the first trigger signal is output, based on data stored in the first data storage unit, and drive the second light emitting unit, in a case where the second trigger signal is output, based on data stored in the second data storage unit.
