Abstract
An image forming apparatus includes a controller configured to, before driving a development motor, obtain a temperature inside a housing from a temperature sensor, determine whether the obtained temperature inside the housing is equal to or lower than a particular temperature, when determining that the temperature inside the housing is higher than the particular temperature, execute a full-speed mode to control the development motor to rotate at a first target speed and control a process motor to rotate at a second target speed, and when determining that the temperature inside the housing is equal to or lower than the particular temperature, execute a low-temperature mode to control the development motor to rotate at a third target speed lower than the first target speed and control the process motor to rotate at the second target speed that is the same as in the full-speed mode.
