An impact resistance is improved and a molding shrinkage percentage is reduced. A thermoplastic resin composition contains: an impact-resistant styrene resin composition which contains polystyrene as a main component and a dispersed rubber phase and in which a volume fraction of the dispersed rubber phaseis less than 30%; dispersed phases of elastomer; and particles of a filler. The dispersed phases of the elastomer contains, as a main component, a styrene-butadiene copolymer serving as a linear copolymer constructed by a triblock consisting of a butadiene block and styrene blocks coupled with both ends of the butadiene block.

In order to suppress such a situation that polyglyceryl fatty acid ester bleeds out at the time of melting of a thermoplastic resin while improving an impact resistance, a thermoplastic resin composition contains a high impact polystyrene, a calcium carbonate as a filler, and polyglyceryl fatty acid ester as a dispersing agent, and a fatty acid constructing the polyglyceryl fatty acid ester is an unsaturated fatty acid.

A process cartridge including a first frame member molded by pouring a resin from a gate; a conductive sheet adhered integrally to a sheet adhering portion of the first frame member by molding of the resin; and a second frame member configured to define a toner storage portion by being coupled with the first frame member, wherein, the first frame member includes a bent portion at the sheet adhering portion, and a portion of the first frame member different in thickness is provided at an adjacent position to the adhering portion.
