The conditions for formation of ion acoustic weak double layer in a dusty plasma are investigated. In case of much
lower value of ion-electron temperature ratio, the weak double layer is observed when the fraction of the negative
charge in the plasma on the dust grain is 
, whereas for equal ion-electron temperature it is observed
only when the fraction is 
. The parameter regimes of transition from compressive to rarefactive double
layer are also specified.
