Composition for accessing a memory in image formation apparatus and method for accessing a memory in image formation apparatus

摘要

A color printer has multiple developing-agent-containing cartridges each having storage units, and a cartridge holding unit for rotatably holding the developing-agent-containing cartridges. With one of the multiple developing-agent-containing cartridges positioned at an image formation position, a latent image on an image carrying member is developed by the developing agent contained in the developing-agent-containing cartridge. An access position where the storage units of the developing-agent-containing cartridges are accessed is a position other than the image formation position. This provides an image formation device and a control method thereof whereby storage units provided to developing-agent-containing cartridges can be accessed in a precise manner.
