Abstract
To provide a semiconductive roller which, when being used as a developing roller in combination with a positively chargeable toner, is capable of suppressing adhesion of the toner thereto to suppress reduction of image density, charging the toner to a higher toner charging level to ensure formation of higher-quality images, and suppressing reduction of toner charging level even after continuous repeated image formation to thereby suppress fogging of formed images for a longer period of time.
