摘要： An image forming apparatus includes: a photosensitive element; a writing light source; a conveying unit; a light-emitting unit; a detection unit; a writing control unit; and an adjustment unit. The detection unit detects reflected light from a recording medium. The writing control unit controls the writing light source based on operational timing when a signal output from the detection unit turns to a fixed threshold. The adjustment unit acquires information of a gloss level of the recording medium, and adjusts light emission intensity of the light-emitting unit according to the acquired information of the gloss level in such a manner that a signal output from the detection unit when the light-emitting unit irradiates a plain region of the recording medium approximates a certain reference value.

A method for separating hydrogen using the hydrogen separation membrane and hydrogen separation conditions are selected by a particular procedure. A hydrogen separation membrane formed of the Nb—W—Mo-based alloy membrane. A method for separating hydrogen using the Nb—W—Mo-based alloy membrane and the conditions for separating hydrogen using the Nb —W—Mo-based alloy membrane are set by measuring the hydrogen pressure P of a hydrogen atmosphere for the Nb—W—Mo-based alloy membrane and the dissolved hydrogen content C of the Nb—W—Mo-based alloy membrane at a temperature T; generating a PCT curve associating the temperature T, the hydrogen pressure P, and the dissolved hydrogen content C on the basis of actual measurement data about the three requirements; and setting operating temperature and primary and secondary hydrogen pressure conditions by determining the relationship between the dissolved hydrogen content C and the brittle fracture of the Nb—W—Mo-based alloy membrane on the basis of the PCT curve to evaluate critical dissolved hydrogen content related to hydrogen embrittlement resistance.
