AI Technical Summary

Technical Problem

The increase in the number of ports and types of substrates in an image forming apparatus due to connecting a control unit and multiple storage sections via a single communication line necessitates changing the circuit configuration for each substrate, leading to increased complexity and cost.

Method used

An image forming apparatus with a switching unit that switches the connected object between multiple storage units via a single communication line, allowing shared addresses and consistent circuit configurations across units, thereby reducing the number of ports and substrate types.

Benefits of technology

This configuration suppresses the increase in the number of ports and substrate types, simplifying manufacturing and reducing errors by allowing shared addresses and consistent circuit designs.

Abstract

To provide an image forming apparatus that can suppress an increase in the number of ports in the control unit and an increase in the number of substrate types. [Solution] The image forming apparatus comprises a plurality of drum units 11, a plurality of developing units 12, a control unit 61 that accesses non-volatile memory 51 provided in each of the plurality of drum units 11 and the plurality of developing units 12, and a switching unit 71 that switches the connected object connected to the control unit 61 via a first communication line L1 between a plurality of non-volatile memory 51 corresponding to the plurality of drum units 11 and a plurality of non-volatile memory 51 corresponding to the plurality of developing units 12.
