ABSTRACT:
Electrophotographic toners comprising a resin, a colorant, a charge controlling agent and an offset preventing agent. The resin comprises a copolymer containing at least one of phenyl isopropenyl ketone and its derivatives as a constituting monomer. The copolymer is photodegradable and thus the toners can be are used for recycling paper.
