An electrophotographic photosensitive member has a photosensitive layer formed on a support. A surface layer (or the outermost layer) of the photosensitive layer contains a fluorine-modified organic silicone resin represented by the following average unit formula:

Electrophotographic photosensitive member, and electrophotographic

A toner for electrophotography contains at least a colorant and a binder resin, and (i) contains 0.1 to 15 parts by weight of colorant per 100 parts by weight of binder resin, (ii) has a number average particle size of 0.5 to 6.0 .mu.m, (iii) has a coefficient of variation of 20% or less based on a number distribution, and (iv) has a capsule structure containing a shell layer and a core. The toner has solvent-mixture-soluble resin components extracted with a solvent mixture of ethanol and methyl ethyl ketone wherein the maximum glass transition temperature (Tg1) of a first soluble resin component obtained by extracting until 10% by weight of the total weight of the solvent-mixture-soluble resin components, and the maximum glass transition temperature (Tg2) of a second soluble resin component of the remainder satisfy the following relations:
