| abstract |
The present invention relates to a toner, an image forming method, an image forming apparatus, and a process cartridge. The toner includes: toner particles, each toner particle containing a toner base particle, wherein the toner contains a binder resin and a colorant, wherein the toner base particle has protrusions at a surface thereof, wherein an average of lengths of long sides of the protrusions is 0.1 [mu]m or more but less than 0.5 [mu]m, a standard deviation of the lengths of the long sides of the protrusions is 0.20 or less, and a coverage rate of the protrusions is 30% to 90%, wherein a resin forming the protrusions is prepared through polymerization of a monomer mixture containing at least a monomer having a sulfonic acid group, and wherein the monomer mixture contains styrene in an amount of 90% by mass or more and the monomer having a sulfonic acid group in an amount of 0.1% by mass to 5% by mass. |
