摘要： A toner containing: a non-crystalline polyester resin; a crystalline polyester resin; a releasing agent; a graft-modified polymer; and a colorant, wherein the graft-modified polymer is a polymer having a glass transition temperature of higher than 40° C. but lower than 80° C., and obtained by grafting an acrylic resin onto at least one of a hydrocarbon wax and a crystalline polyester resin, and wherein a SP value of the non-crystalline polyester resin is defined as SP1, a SP value of the crystalline polyester resin is defined as SP2, a SP value of the releasing agent is defined as SP3, and a SP value of the graft-modified polymer is defined as SP4, and SP1, SP2, SP3 and SP4 satisfy relations represented by Formulas (1) to (3): SP1>SP4>SP2>SP3  Formula (1), 0.1
