    Abstract: This invention relates to a negative silver halide photographic element comprising a support and a silver halide imaging layer containing a light sensitive silver halide imaging emulsion, said silver halide imaging layer further comprising a separately precipitated non-imaging intentionally fogged fine grain emulsion and an electron transfer agent releasing compound represented by formula (I): CAR 1 -(L) n -ETA wherein:

    CAR 1 is a carrier moiety which is capable of releasing ―(L)n-ETA on reaction with oxidized developing agent;
    L is a divalent linking group, n is 0, 1 or 2; and
    ETA is a releasable electron transfer agent, and (optionally) a development accelerator releasing compound represented by the formula (II): CAR 2 -(SAM)-NX 1 -NX 2 X 3
    wherein:

    CAR 2 is a carrier moiety which is capable of releasing -(SAM)-NX 1 -NX 2 X 3 on reaction with oxidized developing agent;
    SAM is a silver absorbable moiety attached to the carrier moiety and is released on reaction with oxidized development agent; and
    - NX 1 -NX 2 X 3 is a hydrazine group wherein X 1 , X 2 and X 3 are individually hydrogen or a substituent chosen from alkyl, aryl, carbonyl, or sulfonyl groups with the proviso that at least one of X 1 , X 2 and X 3 is hydrogen.
