1. An image forming apparatus, comprising:
a container unit configured to contain a recording material;
an image forming unit configured to perform image formation onto the recording material conveyed from the container unit;
a motor configured to drive the image forming unit;
a control unit configured to be able to perform a preparatory operation for preparing the image formation by operating the image forming unit in a state in which the image forming unit is driven at a first speed by the motor; and
a first detection unit configured to detect a size of the recording material contained in the container unit,
wherein the control unit is configured to be able to drive the image forming unit at the first speed and a second speed lower than the first speed,
wherein, in a case in which the control unit determines, before receiving a print signal, that a length of the recording material in a width direction orthogonal to a conveyance direction is equal to or larger than a first width by the first detection unit, the control unit executes the preparatory operation while driving the image forming unit at the first speed, and
wherein, in a case in which the control unit determines, before receiving the print signal, that the length of the recording material in the width direction is smaller than the first width by the first detection unit, the control unit drives the image forming unit at the second speed and after receiving the print signal, performs the preparatory operation.
