Toner, toner stored unit, image forming apparatus, and image forming method

A powder comprising:

• base particles;
• and
• external additives deposited on the base particles,
• wherein the base particles comprise a binder resin comprising a crystalline polyester resin,
• wherein the powder satisfies Conditions 1 and 2 below, when a number distribution D of particle diameters of powder particles B generated from one base particle A is calculated from a density a of the base particles A and a density b of the powder particles B, where the base particles A are deposited on an adhesive area and the powder particles B are deposited on mica by feeding the powder into a vacuumed space from an inlet, and allowing the powder to crush against a surface of a substrate having the adhesive area composed of a carbon tape, and the mica disposed in a manner that the surface is orthogonal to a direction connecting between a center of the vacuumed space and a center of the inlet,
• Powder particles B:
• particles detached from the base particles,
• Condition 1:
• when the number distribution D is presented in a graph by plotting the ranges of the particle diameters by 25 nm on a horizontal axis, and plotting the number of the powder particles B on a vertical axis, a maximum value of the number of the powder particles B lies in any one of the ranges by 25 nm that are a range of greater than 125 nm but 150 nm or smaller, a range of greater than 150 nm but 175 nm or smaller, and a range of greater than 175 nm but 200 nm or smaller,
• Condition 2:
• in the number distribution D, the number of particles having particle diameters of 125 nm or smaller is 30% or less.
