摘要： An image forming apparatus includes an image bearing member, a developing member, a controller configured to carry out switching control between a first state in which the developing member is caused to act on the image bearing member and a second state in which the developing member is not caused to act on the image bearing member, a transfer member, and a detector configured to read density information of the recording material. The controller detects a fog density on the basis of a difference in density information between a fog non-occurrence region of a non-image region of the recording material in the second state and a fog occurable region of the non-image region of the recording material in the first state.

摘要： An exposure device includes a board on which a light source for emitting a light beam is mounted and on which a circuit is disposed, a housing that contains an optical system for guiding the light beam, a positioning member that positions the light source relative to the housing in an optical axis direction by contacting a reference portion disposed around the light source, and a deformable portion disposed in a region of the board that is different from a region on which the circuit is disposed. The deformable portion urges the reference portion toward the positioning member by being elastically deformed when the board is attached to the housing.

摘要： A setting apparatus of the present invention is useful in simplifying user operation necessary in setting an inspection item necessary in setting a target of inspection processing of a printed product. For example, if a two-sided printing is set by the user, a setting of print misregistration inspection for inspecting print misregistration between the front side and the back side is allowed to the user, however, if a one-sided printing is set by the user, a setting of print misregistration inspection is not allowed to the user.

摘要： A pattern detection sensor includes a light emitting element for specular reflection, light emitting element for diffuse reflection light, and light receiving element. When turning on the light emitting element for specular reflection to emit light, a light source switching unit keeps off the light emitting element for diffuse reflection light. When turning on the light emitting element for diffuse reflection light to emit light, the light source switching unit keeps off the light emitting element for specular reflection. An offset detection unit detects a difference between a detection timing by specular reflection light and another detection timing by diffuse reflection light as an offset value (mutual detection error).

摘要： A sheet transport device includes an abutment member that moves downstream in a sheet transport direction and against which a leading end of a sheet that has been transported from upstream in the sheet transport direction abuts; and a transport unit that transports the sheet whose leading end has abutted against the abutment member further downstream. The abutment member moves at least to the transport unit in a state in which the leading end of the sheet abuts against the abutment member, and the abutment member is separated from the leading end of the sheet after the transport unit has started to transport the sheet.
