Abstract: In an image forming apparatus, in a case of duplex printing, a sheet is transported toward an image forming device along a sheet transport route, the image forming device forms an image on a first face, which is one of faces of the sheet, a reverse transport device reverses the front and back faces of the sheet and transports the sheet to a position upstream of a show-through reading device in a sheet transport direction, and the show-through reading device reads a second face, which is another face of the sheet. Then the show-through detector decides whether a show-through has occurred, on a basis of the image that has been read.

A filter according to an example embodiment includes: a substrate having a dielectric property; an initial stage coupling part formed on the substrate; and an interstage coupling part formed on the substrate. The initial stage coupling part is formed so that a reflection delay is decreased in accordance with an increase in a passband due to a manufacturing error of the substrate or the interstage coupling part, or so that the reflection delay is increased in accordance with a decrease in the passband.
