Unhu hwekopi hunonyanya kutsanangurwa nekuita kwemukopi, kunzwisiswa kweiyo photosensitive dhiramu, maitiro emuviri emutakuri uye kunaka kweiyo copier toner. Pano isu tinonyanya kusuma kuumbwa uye basa reiyo copier toner. Resin: iyo huru yekufungidzira zvinhu, iyo inoumba chikamu chikuru che toner; carbon black: iyo huru imaging material, ine basa rekugadzirisa kudzika kwemavara, kureva, iyo inonzi dema; magineti iron oxide: pasi pekukwezva kwemagineti yeiyo magineti roller, inogona Kutakura toner inoshambadzirwa pane iyo magineti roller; charge control particles: kudzora huwandu hwekuchaja hwe toner, kuitira kuti toner ibhadhariswe zvakaenzana.
Haasi ese toner akaenzana kureba, uye kwete ese toner anodhinda zvakafanana, uye chimiro che toner chinotarisa kudhinda. Kirasi I toner: nzira yekugadzira yemuviri, tekinoroji yakakura, zvidiki uye yunifomu zvimedu, kuchinjika kwezvakatipoteredza, kukurumidza kudhinda kukurumidza, yakakwira kunyungudika, kwayakarerekera gloss, uye yakachena dema.

Chikonzero chikuru chekuitika kwemagetsi static chinobva pakusangana kwezvinhu zvakasiyana. Huwandu hweiyo static charge inogadzirwa nesechipiri-ruoko copier toner vagadziri huri muhunhu hwezvinhu zviviri izvi. Zvimwe zvinhu zvinoburitsa mari yakawanda yekuchaji kana zvakwizwa. . Iko polarity ye electrostatic charge pachinhu zvakare zvinoenderana nehukama hwezvinhu zviviri zvinokweshana. Kana nzvimbo dzezvinhu zviviri zvakasiyana dzichisangana, mhosva dziri pakati padzo dzichagadziriswazve, uye kuchinjana kweelectron kuchaitika panguva ino. .
