## Abstract

A toner including: a toner particle, wherein the toner particle contains a binder resin, a compound represented by formula (1) below, and a compound in which at least a compound represented by formula (2) below and a compound represented by formula (3) below are in solid solution. In formula (1), R1, R2, R3, and R6 each independently represent an alkyl group or aryl group, and R4 and R5 each independently represent an aryl group, acyl group, or alkyl group, or R4 is bonded to R5 to form a cyclic organic functional group that contains R4, R5, and the nitrogen atom to which R4 and R5 are bonded.

## Claims

### Claim 1

A toner comprising a toner particle, wherein
the toner particle contains
a binder resin;
a compound represented by formula (1) below; and
a compound in which at least a compound represented by formula (2) below and a compound represented by formula (3) below are in solid solution;
in formula (1), R1, R2, R3, and R6 each independently represent an alkyl group or aryl group, and R4 and R5 each independently represent an aryl group, acyl group, or alkyl group, or R4 is bonded to R5 to form a cyclic organic functional group that contains R4, R5, and the nitrogen atom to which R4 and R5 are bonded.

### Claim 2 (depends on 1)

The toner according to claim 1, wherein the binder resin contains a polyester resin.

### Claim 3 (depends on 1)

The toner according to claim 1, which satisfies the following formula, wherein A is the content (mass parts) of the compound (1) and B is the content (mass parts) of the compound in which at least the compound (2) and the compound (3) are in solid solution.
0.005≤A/B≤10.000

### Claim 4 (depends on 1)

The toner according to of claim 1, wherein, in formula (1), R1 and R2 are each independently an alkyl group having 1 to 15 carbon atoms; R3 is an alkyl group having 1 to 6 carbon atoms or is a group represented by formula (4) below; R6 is an alkyl group having 1 to 10 carbon atoms; and R4 and R5 are each independently an alkyl group having 1 to 6 carbon atoms, an alkylcarbonyl group having 2 to 10 carbon atoms, or an arylcarbonyl group having 7 to 11 carbon atoms;
in formula (4), R7 and R8 each independently represent a hydrogen atom, an alkyl group having 1 to 6 carbon atoms, or an alkoxy group having 1 to 6 carbon atoms. R9 represents a hydrogen atom, alkyl group, or alkoxy group.

### Claim 5 (depends on 1)

The toner according to claim 1, wherein the toner particle contains a graft polymer having a structure in which polyolefin is grafted to a vinyl resin component and/or a graft polymer having a structure in which a vinyl monomer is graft polymerized to a polyolefin.

### Claim 6 (depends on 1)

The toner according to claim 1, wherein the toner particle contains a hydrocarbon wax.
