Coating agents for electrophotography carriers are disclosed which are resistant to wear, peel-off, cracks, and prevent the occurrence of a spent phenomenon, and which possess a durability for a long period of use and a superior stability in the carrier charge characteristics; the coating agents are characterized by having as a main component an organopolysiloxane of formula below: R<f>aR<1>bSi(OR<2>)cO[4-(a+b+c)]/2 wherein R<f> is a group CpF2p+1Q, in which p is an integer of 1 to 12, and Q is a bivalent organic group with 2 to 12 carbon atoms, R<1> is an alkyl group with 1 to 12 carbon atoms or phenyl, R<2> is an alkyl group with 1 to 6 carbon atoms, and a, b and c are numbers which satisfy the following conditions: 0 < a </= 1, 0 </= b < 2, 0 </= c </= 3 and 0 </= a+b+c </= 4. |
