Abstract
Procedeul conform inventiei se refera la obtinerea developerului pentru masini electrostatice de copiat cu developare magnetica, folosind tehnica pretratarii unor pulberi magnetice cu solventi organici halogenati, în prezenta de ultrasunete, si apoi uscare 12 h la 60...90 degree C în vid, dupa care se acopera în mod continuu cu un copolimer sau terpolimer în solutie, la 90...100 degree C, cînd are loc evaporarea solventului, developerului perfect uscat se mentine la 60...80 degree C timp de 12 h, astfel rezultînd particule cu o grosime a stratului depus de 0,2...1 mu m si o încarcare electrostatica a developerului de 13...30 mu c/g.
