Abstract
An image forming device includes: an endless intermediate transfer belt; and a secondary transferrer, wherein the secondary transferrer includes a secondary transfer roller and a counter roller, a value calculated from w/Vis defined as a nip time N [sec], when the secondary transferrer is deemed as an equivalent circuit including a resistance R1 [Ω·m] of the secondary transfer roller, a resistance R2 [Ω·m] of the intermediate transfer belt, a resistance R3 [Ω·m] of the counter roller, and capacitance C[F/m] of a recording medium, in a case where a combined resistance in the equivalent circuit is defined as R[Ω·m], and combined capacitance in the equivalent circuit is defined as C[F/m], a value calculated from R×Cis defined as a time constant τ [sec], and the image forming device further includes: a sheet detector; and a hardware processor.
