Claim Text:
1. A drawing apparatus for performing drawing on a substrate with a plurality of charged particle beams, comprising: a blanker array including a first blanker and a second blanker, the first and second blankers being configured to respectively control blanking of a first charged particle beam and a second charged particle beam out of the plurality of charged particle beams; a deflector configured to deflect charged particle beams which have passed through the blanker array out of the plurality of charged particle beams to scan the charged particle beams on the substrate in a scanning direction; and a controller configured to supply a control signal to the first blanker at a first timing and supply a control signal to the second blanker at a second timing different from the first timing, wherein a period between the first and second timings is shorter than a period in which one charged particle beam is scanned by the deflector across a dimension in the scanning direction of one pixel, and the second blanker is arranged at a position shifted from a position of the first blanker in the scanning direction by an amount corresponding to a distance by which the charged particle beams are scanned by the deflector in the period between the first and second timings.
