Image forming apparatus

An apparatus including a forming unit configured to form an image onto a recording medium, the apparatus comprising:

• a receiving unit configured to receive an instruction to start reading of a document;
• a reading unit configured to read an image on the document based on the received instruction;
• a memory configured to store a plurality of pieces of pixel data corresponding to a reading result of the reading unit, the read image being represented by a plurality of pixels, and each of the plurality of pieces of pixel data being data per pixel;
• a first output unit configured to output a synchronizing signal;
• a second output unit configured to start output of the stored plurality of pieces of pixel data based on the synchronizing signal, the second output unit outputting a predetermined number of pieces of pixel data within one cycle of the synchronizing signal;
• a data bus configured to transfer the plurality of pieces of pixel data;
• and
• a controller configured to operate a first process of transferring the plurality of pieces of pixel data output from the second output unit, to the forming unit via the data bus, and a second process of converting data input from an external device of the apparatus, into a plurality of pieces of pixel data for forming an image onto the recording medium, and transferring the converted plurality of pieces of pixel data to the forming unit via the data bus,
• wherein the forming unit forms an image onto the recording medium based on the plurality of pieces of pixel data transferred via the data bus,
• wherein the controller sets a cycle at which the synchronizing signal is output as a first cycle in a case where the receiving unit receives the instruction while the controller is not operating the second process, and
• wherein the controller sets the cycle at which the synchronizing signal is output as a second cycle longer than the first cycle in a case where the receiving unit receives the instruction while the controller is operating the second process.

• wherein, in a case where the receiving unit receives the instruction while the controller is not operating the second process, the controller sets an output cycle at which the first output unit outputs the plurality of pieces of pixel data corresponding to the read image based on the instruction as a first cycle in a case where a resolution of the image to be formed by the forming unit is a first resolution, and
• wherein, in a case where the receiving unit receives the instruction while the controller is operating the second process, the controller sets the output cycle as a second cycle longer than the first cycle in a case where the resolution of the image to be formed by the forming unit is a second resolution higher than the first resolution.
