    摘要: An image forming apparatus includes a latent-image forming unit that forms an electrostatic latent image onto an image carrier, a developing member that develops the electrostatic latent image held on the image carrier with a developer, a container that contains the developer supplied to the developing member, a stirring member that stirs the developer by rotating in the container, a density detecting unit that is disposed in the container and that detects a density of the developer, and a switching unit that switches an image formation condition by using a period of a signal output by the density detecting unit.

    摘要: An image forming apparatus includes first and second rotating members, a setting unit, and first and second image forming units. The first rotating member rotates at a first period T1. The second rotating member rotates at a second period T2. The setting unit sets the first period T1 and the second period T2 so that T1 and T2 meet a relation T2=(n+0.5)×T1 (n is a positive integer). The first image forming unit forms a first image on the second rotating member in an x-th rotation (x is a positive integer) using first data obtained from print data and using the first rotating member. The second image forming unit forms a second image on the second rotating member in an (x+y)-th rotation (y is an odd positive integer) using second data obtained from the print data and using the first rotating member.

    摘要: An image processing apparatus includes a receiver and a correcting unit. The receiver receives a first read value and a second read value. The first read value indicates a result of reading a first color by a reader from a recording medium in which the first color is applied to a first area in which in-plane density unevenness is confirmable within the recording medium. The second read value indicates a result of reading a second color by the reader. The second color is different from the first color and is applied to a second area that is substantially the same as the first area in a superimposed manner. The correcting unit corrects in-plane density unevenness of the second color applied to the first color in the superimposed manner based on the first read value received by the receiver and the second read value received by the receiver.
