A process for manufacturing a thermoplastic resin composition by melt-kneading a thermoplastic resin and fine particles or an additive, includes: introducing gaseous and/or liquid fluid containing fine particles of at most 10 .mu.m particle diameter or an additive to an unmelted granular or molten thermoplastic resin moving bed; adhering or depositing the fine particles or additive onto said moving bed, while the fluid in the gaseous state is being discharged; and then successively melt-kneading a mixture of the granular resin with the fine particles or additive. This process can be combined with a subsequent shaping step continuously that follows. The process of the invention saves energy, raw materials and labor consumptions and yields shaped articles of high quality and uniformity.
