Precise correction of a position of a toner image formed by an image forming station can be accomplished in a device using two-component developer. An electrostatic latent image for forming a color misregistration correction pattern for color misregistration correcting includes a first latent image pattern and a second latent image pattern at a position downstream of the first latent image pattern with respect to the moving direction of the electrostatic latent image. The toner image resulting from the development of the first latent image pattern has a width, measured in the image moving direction, which is greater than that of the toner image resulting from the development of a latent image pattern alone, which is the same as the first latent image pattern, or the toner image resulting from the development of the first latent image pattern has an image density at a downstream end portion with respect to the moving direction, which density is higher than that of the toner image resulting from the development of the latent image pattern alone, which is the same as the first latent image pattern.
