Abstract
PURPOSE: To form the captioned carrier material which forms the covering film of high strength and hardness and show stable chargeability to humidity change by making surface treatment with the partial hydrolysis product of the specific alkoxy silane mixture.
CONSTITUTION: The mixture of 1 pt.wt. of the alkly tri alkoxy silaine (preferably methyl trimethoxysilane) shown by general formula I (R is alkly of C1-4) and 0.01 to 0.4pt.wt. of the tetraalkoxy silane (preferably tetraethoxysilane) shown by general formula II is hydrolyzed at room temperature in the presence of catalyst in a solvent such as alcohol, dioxane, etc., whereby the partial hydrolysis product is formed. Next, the solution of the abovementioned partial hydrolysis product is sprayed to magnetic particles of iron, steel, etc. of about 50 to 150μ in particle sizes and is then dried, whereby the film is formed. Here, the amount of using the hydrolysis is preferably about 5 to 56.6pts.wt. in dry pick-up per 1000pts.wt. of magnetic particles.
