An image forming apparatus includes a mechanism configured to bring an intermediate transfer member into a first state contacting first and second drums and a second state separating from the first drum and contacting the second drum. The image forming apparatus is operable in a first mode of using the first and second drums in the first state, a second mode of using only the second drum in the second state, and a third mode of using only the second drum in the first state. If an image forming retry involving cleaning a transfer portion due to a recording medium conveyance delay in the third mode is to be performed, a controller changes over the third mode to the second mode without stopping rotation of the second drum to perform image formation on a recording medium fed by restart of a feeding operation.

Image forming apparatus

An image forming apparatus includes an obtaining unit configured to obtain information related to a resolution of an image to be formed, an image processing unit configured to execute image processing corresponding to the information on image data, an image forming unit configured to form an image based on the image data on which the image processing is executed by the image processing unit, an intermediate transfer member to which a measuring image formed by the image forming unit is transferred, a measurement unit configured to measure the measuring image transferred to the intermediate transfer member, a storage unit configured to store measuring image data, and a controller configured to control the image processing unit to execute first image processing on the measuring image data, control the image forming unit to form the measuring image, control the measurement unit to measure the measuring image, and control an image forming condition.
