Summary: We generalize our recent results on the boundedness and compactness of Toeplitz operators to the Bergman space $A^1$ on the unit disc. While the natural condition for the symbols leads to $BMO_\partial$-type symbol classes, the inevitable logarithmic correction for the nonreflexive case requires a separate treatment of $BA$-and $BO$-type symbols.

Keywords: Toeplitz operator, boundedness, compactness, bounded mean oscillation, Bergman space $A^1$
