Description

上記目的を達成するために、請求項１の発明は、潜像担持体と、該潜像担持体に作用する１つ以上のプロセス手段とを筐体に収納した複数の作像ユニットであって、上記プロセス手段として上記潜像担持体を除電する除電手段を有し、上記潜像担持体表面に潤滑剤を塗布する潤滑剤塗布手段を有さない第一の作像ユニットと、上記プロセス手段として上記潤滑剤塗布手段を有し、上記除電手段を有さない第二の作像ユニットとを備え、上記第一の作像ユニットの筐体と上記第二の作像ユニットの筐体を、同一の構成にしたことを特徴とするものである。 To achieve the above object, the invention of claim 1 is a plurality of image forming units in which a latent image carrier and one or more process means acting on the latent image carrier are housed in a housing. A first image forming unit having a charge removing means for discharging the latent image carrier as the process means, and having no lubricant applying means for applying a lubricant to the surface of the latent image carrier; and the process means. A second image forming unit having the lubricant applying means and not having the charge eliminating means, and a housing for the first image forming unit and a housing for the second image forming unit. It is characterized by having the same configuration .

本発明においては、プロセス手段の異なる構成の第一の作像ユニットの筐体と、第二の作像ユニットの筐体とを同一の構成とした。これにより、一つの金型で、第一の作像ユニットの筐体と第二の作像ユニットの筐体を製造することができる。また、ひとつの製造ラインで、第一の作像ユニットの筐体と第二の作像ユニットの筐体とを製造することができる。よって、第一の作像ユニットの筐体と第二の作像ユニットの筐体とを互いに異ならせた場合に比べて、製造コストを下げることができる。
また、一方の作像ユニットの再利用可能な筐体を、他方の作像ユニットの筐体に再利用することできる。これにより、第一の作像ユニットに用いられた再利用可能な筐体と、第二の作像ユニットに用いられた再利用可能な筐体とを一括で管理することができ、管理コストの低減を図ることができる。また、再利用可能な筐体の在庫不足や在庫余りを抑制することができ、作像ユニットの筐体を再利用の効率を高めることができる。
In the present invention, the casing of the first image forming unit and the casing of the second image forming unit having different configurations of the process means have the same configuration. Thereby, the housing of the first image forming unit and the housing of the second image forming unit can be manufactured with one mold. Moreover, the housing of the first image forming unit and the housing of the second image forming unit can be manufactured on one production line. Therefore, the manufacturing cost can be reduced as compared with the case where the housing of the first image forming unit and the housing of the second image forming unit are different from each other.
Further, the reusable casing of one image forming unit can be reused as the casing of the other image forming unit. As a result, the reusable casing used for the first imaging unit and the reusable casing used for the second imaging unit can be managed in a lump. Reduction can be achieved. In addition, it is possible to suppress a shortage of inventory and surplus inventory of reusable casings, and it is possible to increase the efficiency of reusing the casing of the image forming unit.
