A color image forming apparatus configured to form a latent image on a photosensitive drum and form an image by developing the latent image with developer, comprising: forming means adapted to perform image forming in accordance with a plurality of image forming modes, each image forming mode corresponding to a recording medium type; detecting means adapted to detect a color patch formed on a recording medium by the forming means; and control means adapted to determine whether to set an image forming condition, and adapted to set, on a basis of a result of detection by the detecting means, an image forming condition for the image forming performed by the forming means, wherein the control means is configured to: in a case where the color patch is formed in a first image forming mode by the forming means, determine whether an image forming condition in a second image forming mode is to be set or not, in a case where it is determined that the image forming condition in the second image forming mode is not to be set, not set the image forming condition in the second image forming mode on the basis of the result of the detection of the color patch formed in the first image forming mode, and continue to use, as the image forming condition in the second image forming mode, an image forming condition that has already been set, and in a case where it is determined that the image forming condition in the second image forming mode is to be set, set the image forming condition in the second image forming mode on the basis of the result of the detection of the color patch formed in the first image forming mode. forming means adapted to perform image forming in accordance with a plurality of image forming modes, each image forming mode corresponding to a recording medium type; detecting means adapted to detect a color patch formed on a recording medium by the forming means; and control means adapted to determine whether to set an image forming condition, and adapted to set, on a basis of a result of detection by the detecting means, an image forming condition for the image forming performed by the forming means, wherein the control means is configured to: in a case where the color patch is formed in a first image forming mode by the forming means, determine whether an image forming condition in a second image forming mode is to be set or not, in a case where it is determined that the image forming condition in the second image forming mode is not to be set, not set the image forming condition in the second image forming mode on the basis of the result of the detection of the color patch formed in the first image forming mode, and continue to use, as the image forming condition in the second image forming mode, an image forming condition that has already been set, and in a case where it is determined that the image forming condition in the second image forming mode is to be set, set the image forming condition in the second image forming mode on the basis of the result of the detection of the color patch formed in the first image forming mode. in a case where the color patch is formed in a first image forming mode by the forming means, determine whether an image forming condition in a second image forming mode is to be set or not, in a case where it is determined that the image forming condition in the second image forming mode is not to be set, not set the image forming condition in the second image forming mode on the basis of the result of the detection of the color patch formed in the first image forming mode, and continue to use, as the image forming condition in the second image forming mode, an image forming condition that has already been set, and in a case where it is determined that the image forming condition in the second image forming mode is to be set, set the image forming condition in the second image forming mode on the basis of the result of the detection of the color patch formed in the first image forming mode.
