A radiation curable dry toner comprising core-shell toner particles, wherein the core-shell toner particles have an average volume-based diameter between 5 and 10 micrometre, wherein a core-shell toner particle thereof comprises: a. an inner portion comprising a radiation curable first resin material consisting of at least 90 weight%, preferably at least 95 weight%, of the total amount of resin material of the inner portion; b. an outer shell surrounding said inner portion, said outer shell comprising a second resin material, said second resin material being any one of the following: - cured first resin material; or - a resin material which is different from the first resin material; wherein the second resin material of the outer shell is coalesced with the first resin material of the inner portion; and wherein the resin material of the inner portion and of the outer shell are chosen such that the dry toner has a melt viscosity of less than 1000 Pa.s at 120°C, measured at a frequency of 1 Hz and an amplitude of 0.005 radians, wherein the second resin material has a higher melt viscosity than the first resin material; and such that the dry toner has a storage stability of at maximum 100 g/kg; wherein the storage stability is determined by shaking 20 g of the dry toner in a 50 ml bottle, followed by conditioning the dry toner for 40 hours at 40°C, whereupon the dry toner is manually sieved over a 300 μm sieve and the amount of toner remaining on the sieve is weighed and expressed as g/kg toner versus the original amount of 20 g. a. an inner portion comprising a radiation curable first resin material consisting of at least 90 weight%, preferably at least 95 weight%, of the total amount of resin material of the inner portion; b. an outer shell surrounding said inner portion, said outer shell comprising a second resin material, said second resin material being any one of the following: - cured first resin material; or - a resin material which is different from the first resin material; wherein the second resin material of the outer shell is coalesced with the first resin material of the inner portion; and wherein the resin material of the inner portion and of the outer shell are chosen such that the dry toner has a melt viscosity of less than 1000 Pa.s at 120°C, measured at a frequency of 1 Hz and an amplitude of 0.005 radians, wherein the second resin material has a higher melt viscosity than the first resin material; and such that the dry toner has a storage stability of at maximum 100 g/kg; wherein the storage stability is determined by shaking 20 g of the dry toner in a 50 ml bottle, followed by conditioning the dry toner for 40 hours at 40°C, whereupon the dry toner is manually sieved over a 300 μm sieve and the amount of toner remaining on the sieve is weighed and expressed as g/kg toner versus the original amount of 20 g. - cured first resin material; or - a resin material which is different from the first resin material; wherein the second resin material of the outer shell is coalesced with the first resin material of the inner portion; and wherein the resin material of the inner portion and of the outer shell are chosen such that the dry toner has a melt viscosity of less than 1000 Pa.s at 120°C, measured at a frequency of 1 Hz and an amplitude of 0.005 radians, wherein the second resin material has a higher melt viscosity than the first resin material; and such that the dry toner has a storage stability of at maximum 100 g/kg; wherein the storage stability is determined by shaking 20 g of the dry toner in a 50 ml bottle, followed by conditioning the dry toner for 40 hours at 40°C, whereupon the dry toner is manually sieved over a 300 μm sieve and the amount of toner remaining on the sieve is weighed and expressed as g/kg toner versus the original amount of 20 g.
